zapfanzapfan : Showing the slides would just be stupid?...

rediornot : why aren't we seeing any of his slides?

Memento Mori : People need to relax. Neil makes legitimate points here. He has nothing against private enterprise or Musk; he simply is skeptical that they will be what drives space exploration. You can disagree with that, but don't dismiss it by shitting on Neil. Chill.

Glenn Runnalls : His whole argument is based on the money to do it. Which space x has figured out by cutting cost with reusable rockets. Plus they make the money from launching satellites and other things like human transport to the ISS in the future. Yeah it’s hard for NASA to launch 400 million dollar rockets then crash land them every time. Not to mention space x doesn’t have to deal with the politics, because they aren’t a government agency. He says he’s being a realist, while ignoring large facts and factors on why it can work. Plus I should add that the falcon heavy only cost 90 million. it’s re usable, unlike nasa building 300-500 million dollar rockets. then smashing them into the ground.

Hansen Nansen : People in this commentsection is so insanely stupid. Neil isn't a nosayer to space exploration. How can people construct such an unfair and stupid thought?? Read "Space chronicles" ffs! All he is doing is setting it straight between private enterprice, statefunded endeavors and people's uninformed and naive expectations for the future of space, because of Elon's lunch. To really progress in spaceexploration, people need to start educate themselves and become scientist and engineers, not going around in a dreamstate screaming "Elon made a spacelunch, now we are going to live in space, halleluja". We need a new culture where people think critically, take care of their health, work hard with honesty and become responsible for the country's future, instead of luying in bed just in the underwear, eating mcdonalds, watching youtube and netflix before going out pretending that they know something.

Marcos Nogueira Martins : I thought Elon Musk fans would understand science... And I'm sure most comments here were written without listening to the video

Oğuzhan Öztürk : I love Neil but am really dissapointed hearing all these.. I am not a typical fanboy and Neil's argument here has a bunch of realistic big holes in it.. lets go through some of them together.. why would we do this? either if we stay we gonna die or someone will make a buck out of it.. well lets look around ( not with stupid trump eyes but with normal ones ) how is it going with the planet? we are accelerating everyday towards some major, most likely selfmade destruction. Even if we somehow manage to save the planet the nature, people will still be interested in making a buck out of it and no it wont be because of tourism only. Lets say we have 4 people on mars and a bunch of small big different equipment and while these people are trying to grow tomatoes or going around searching stuff they will start coming across different materials different finds etc..meanwhile sending the second group will be cheaper to send there since there is already a base which needs some upgrade.. now we have 8 people and the second group came with some new equipment which will allow them to start building stuff there on their own.. and the third and the we have a lot more rockets taking off landing it will get cheaper and one day even bringing material will be profitable depending on how important the material is. Since people can watch and see what is going on they dont have to come back or even survive to convince people back home that it is worth to go there if it is the case.We are not waiting colombus from the ocean without even electiricity. In the freaking 9 months while you are on the way to mars there will be a bunch of new technologies coming out to begin with. If there were people on mars or moon we would love to put up some nice telescopes up there which we can actually maintain upgrade and service day in day out unlike telescopes in orbit or outter space.Even if i just convince some super rich adrenalin freaks to go there as tourists, the knowledge gathered the findings the experience all that stuff is worth supporting those freaks. All kinds of data will be added to our archieves and people like Neil will have more to work with. One day someone like Neil will say " someone called elon musk was a weir dude and he tought X was possible and while trying they found Y out and didnt know back then what Y ment.. but thank god they found it and today we finally understood it and bla bla bla.. It is a freaking win win win situation where you cant lose as humanity even if you couldnt come back and lost in deep space. Companies will be running after this asteroid that asteroid to dig whatever material they need. As far as i know settling somewhere means you live there you work there you create there so it should not be like sitting around doing nothing. Maybe they build a brick wall first to keep the place safe from heavy dust storms..maybe we send them a 3d printer of somekind which they can build stuff from the material they have on the mars surface.. If we keep supplying everything from the earth with limited resources with a big gravity against lifting stuff etc.. yes it would be a kind of masturbation but costs cant stay like this in front of innovation.. even the stupid space elevator idea is becoming more and more considerable everyday.. Maybe we dont need settlement there but we need this experience.. maybe we will never need another planet to live on but we will need stations to travel, we need to go to places to learn and discover, we need to be able to go mine materials and harvest different energy sources in order to achieve human goals and answer the needs to survive. I always tought of having a station on the moon to launch heavy cargo to earth which was brought to moon from asteroids or mars etc. I mean come ooooon there are millions of ways to make it profitable and as many reasons why it is necessary. Why try to find a way to get rid of an asteroid the first time while you could already be able to go live elswehere while you could be already resourcefull and rich and well advanced that getting rid of that asteroid would not be a big deal at all?? We are not talking what is or is not possible for this very moment so the ideas might seem like a dream.. But remember he was coming to date from 1900 predictions on 2000s so we are talking about the next 100 years pretty much. These are not dreams and Neil is being a bit too pessimistic about it instead of realistic. There is no question he wants it all to happen tho.. he is a scientist he would say yes anyday if you were investing in science, he just thinks you wont and it wont one will go and or settle..

medviation : Elon Musk is not predicting the future. He's building it the way he wants it. Neil will choke on his words when Elon actually builds a Mars colony.

ItsMe NoName : maybe first....try to build a base on the moon. or even better....lets try to go to the moon.

Argasy Argasy2 : Lets face it Neil. Elon doesnt care what your opinion is, hes going to Mars and come hell and high water he will do it! Its not about profit for him, its his damn dream and has made it the dream of many many more people out there! Btw Neil, be careful of absolutes. BTW. Neil looks abit winded or tired when talking about space x.

Shreyas Malde : Neil Degrasse Tyson is not pro space, he is just pro NASA! If he was really pro space, he would support the developments made in space irrespective of whether it is done by government or private sector!

Bedtime Paradox : You spent years on talkshows and podcast criticizing the goverment because they dont give enough money for space exploration. But your opinion about SpaceX is complete the opposite. Despite all the success that they show, year after year, you just keep criticizing them. Please explain all that hate… I have just stop following your talks because you have just lost the credibility .

Son of Jorel : Neil assumes there will be no profit in space, but that may be his number one fallacy. Once the right company finds a way to make a profit on the moon or Mars, others WILL follow. PROFIT,. is going to make the universe go round d.

SGTBizarro : Come on, Neil... you're supposed to be a champion of discovery and exploration. It may not be likely in the short term, but unless we blow ourselves up, the exploratory drive makes it inevitable, especially for those who have the means and the ambition to do it.

Syd Syko : Then along came Elon Musk and said *watch this*

No Name : I hope Elon Musk will make a colony on Mars and prove everyone wrong

ValhalaFiveSix : All these morons who said in this thread Tyson is wrong then explain why we haven't been back to the moon in over 50 years? Why there are no corporations period on the moon? Mining or space tourism or anything? We have had 50 years half a century to build a moon base, we could have put telescopes, mined, shot reality shows, yet there is nothing by man going on on the moon. You people don't understand reality.

Nicholas Veridiculity : Niel is correct to assume that any enterprise seeking to bring people to other worlds would require significant funding initially. He is also correct in pointing out historical precedents for the allocation of such funding. People are saying that Niel Tyson's realism, among these facts, is downplaying or mudslinging toward enterprises such as Elon's, but he's only pointing out the difference between the hype Elon takes advantage of and the reality of any immediate future.

Josef Janoušek : I just want to hear laugh of Elon watching this video..

Maria Jimena : I think deep down Neil is jealous of Elon's dream coming true. Is normal for humans to have these emotions and he has a really polite way to handle it. But I think he should be helping to find solutions not problems.

master7chief : Why all the down votes? I get that some don't like his skeptical sounding opinion but as he stated, he's a realist; he did not diminish what SpaceX accomplished. He's simply reminding us that while the reusable design is now proven, the greater issue is that the private sector does not have strong enough economic justification for space colonization and that's where we may be misguided in our space goals. Asteroid diversion and mining would be more technologically and economically beneficial than colonizing a naturally uninhabitable place. Dr. Tyson asks WHY populate a place less inhabitable than Antarctica considering no one is lining up to go there and it actually has breathable air among other things. How does that = a down vote? Everyone is suddenly energized after last week including myself, and rightfully so, but what will we ultimately to do with our economic resources once the excitement wears off? I think that's the point he's making.

Daniel Bohatkiewicz : My brother told me this 25 years ago. -Me, "Why don't we go back to the moon?". His answer, "Cause there weren't gold nuggets and diamonds all over the ground when we got there.".

Stan Jones : Why is Tyson speaking out now against the space program? In 2012 he was such a strong advocate for space when he made a very articulate and convincing argument to the U.S. senate based on practicality. What happened?

briancnc : Neil is an academic, plain and simple. They deal with theology more than reality. Spacex has proven a lot of these guys wrong before and I suspect many times over in the future. If you left the future of innovation, exploration, and disruption up to academic types the world would never change. The world needs more engineers not political science studies.

wayneyd2 : Neil deGrasse Tyson need to shut up. He has no vision on anything.

Donavan LoForte : Here's my two cents. $0.02.

doctorale666 : NDT is correct, can't blame him for saying the truth. SpaceX came up with some impressive technology that is true (financed with the government's help through many contracts) but they didn't pioneer anything, so far all they did is low Earth orbit, that stuff was done back in the 50s! oh and overshot a car into the asteroid belt and that about it. To top it all off the Falcon Heavy wasn't even a complete success. Now I'm all up for this cool stuff but lets temper our expectations a little here, SpaceX haven't even managed to put a dog in space let alone humans on Mars, come on people.

Alec Jordan : The video with the slides has been removed by the uploader. This is very displeasing.

oneplot : i think people are wrong to accuse him of been anti space exploration, rather he is making the case for a more intelligent use of space development

Dan Mog : We're not gonna be able to do shit if people like you are constantly trying to kill the incentive and the momentum. Ambition is key to progress. We're on the right pace to colonizing other worlds in the solar system, Plus if we're gonna stay on earth forever and not try to get the most fundamental of answers then what is the point of doing science and tech anyway. It is very shameful, indecent and lazy standing around saying we can't. Really depressing to hear these words come out the mouth of a Man like you.

Oscar Moreno : Carl Sagan would have been very disappointed in his pupil. I wonder if this is the view of his other mentor Ann Druyan? I usually like Everything Neil says and (almost) everything he says here is right - EXCEPT . . . . . POINT# 1: We don't need a war anymore SpaceX is not publicly traded company. So there are no venture capital meetings or investors to appease. As a private company, spaceX is poised to do whatever the hell it wants with it's (large) sums of revenue from satellite, government, and military contracts. That is where Neil has missed the boat. POINT #2: Engineering problems don't solve themselves NASA engineers swore on their mother's graves that reusable rockets would "NEVER, EVER" happen because of physics. Then Musk did it. Then the argument shifted to "THEY WOULD NEVER BE ECONOMICAL". Then Musk launched 18 times in 2017. Then the argument shifts to weather the Flacon Heavy and BFR are viable rockets. I will guess that the bar will continue to adopt to every success. POINT# 3: NASA NASA does well on deep space and discovery missions. But as long as human spaceflight is tied to the politics of Washington, NASA has it's hands tied. SpaceX is free of politics. FINAL POINT: I will repeat what I've been saying for decades now: If spaceX ever goes Public, it is going to be the end of the innovative company as we know it today.

Nikola Tesla : He came up with 3 reasons for doing extraordinary activities , here's a fourth: When certain individuals work extremely hard to come up with revolutionary ideas for the benefit of mankind as whole, THEN civilization makes the most progress. That's the first thing you should've noticed when taking cues from history. All the fundamental discoveries in science and innovations in technology that changed everyone's lives, were done by a few dozen people total, and the rest of the billions of people including the ones who came after them, depends on their work. That's what we have with Elon Musk. He wanted to transform online payment methods, so he created PayPal. He wanted sustainable energy transport, he created Tesla. He wants to make space cheaper, that's why he fucking created SpaceX. All of his work is on the frontier of science and yes he is, a private individual.

OldGamerNoob : Financial Return - - now going to the moon for mining He3 and other stuff (maybe will get us to mars once that threshold is crossed) War - - MAYBE China vs. USA Royaly funded and Deity required - - Elon Musk

Oscar Moreno : This reminds me of the argument that Television broadcasters made some ten years ago when Youtube was first founded: -"It will never amount to anything. The common folk just does not have the money, skills, or the knowledge to make videos that can capture the public 'en masse'". Well, well.... look where we are now.

UNSTOPPABLE-AR MARI : Neil, I don't wanna lose respect for you, please apologize for all the critics you made against Elon Musk and acknowledge that you were very negative about the whole private investment to space. That doesn't make you a less of a man, only a better one.

cax Mopart : Having in mind how slow is Nasa and other countries in the last 50 years, Elon is the only chance to see anything interesting in our lifetimes. Neil, you are simply being annoying and uninspiring, just the opposite to what you are suppose to be.

Screwy17 : I've seen parts and variations of his speech, and I'm lucky to have some imagination. But it would've been nice to see the slides he was talking about.

Edgardo Heredia : Neil is not hating he is just being honest...he is just diluting the hype and showing that space exploration is not all cup cakes and rainbow...that there is real danger and is more difficult that people think...he also said that a lot of the things being done in space today should have been done 20 years ago...

Monica Hall : Most people here seem not to have listened to Neil very closely. He's not against space exploration at all - he knows it's a great driver of science. But he does understand the politics and economics of it, and is not as gung-ho as others are about how to get it funded or its likely timeline. I dare say we'll muddle through eventually, as we always seem to, though it probably won't be as soon or as easy as Elon tells us (I'm a fan of his incidentally). Elon has a dream and he's made enough money to make it seem possible, but he still might not ultimately be the one to realize it sadly - due to geopolitics - but would he think that his life's work had been futile? I don't think so.

dean wright : Niel de Grasse tyson is a liar and a fraud.

lessdeth69 : I would like to see our species "not die" from a major comet, or meteor impact.

jerrylittlemars : Great talk, but the cameraman sucks at his job. He missed all the slides Neil was showing on the screen

final fandy : .. outside of the surface of the Earth, the universe is a harsh and dangerous place for us human life .. if you spray a bowling ball with a thin coat of paint, then enlarge the ball to Earth size then almost all history of humanity is within that thin coat (apart from space travels that is) including the deepest oceans, highest mountains and .. the clouds that jet planes fly over .. they are all within that thin coat. .. yes, like Neil said here, we still have a long way to go .. a lot more problems to solve; but we can't just expect Ironman do the fight alone while we watch on, popping in pop-corns and cheer. Its not a one man show. Colonizing another planet is colonizing the universe .. its no small feat.

mateo : He was the one complaining about nobody dreaming about space anymore... he has so much influence to really guide public opinion towards the importance of what SpaceX is doing (even if they fail), but now he’s become the “realist naysayer”. What a shame.

Marlon : Neil’s starting to piss me off

SKINZ GAMING : Whos Elon Musk?

Secular Sam : I'm sure most people who disliked the video didn't watch it full.

Abid Din : Everyone in the comment section is emotional. Neil is reasonable. I'll take reason over emotion any day.

ThisNoName : So Neil's vision for AI is the perfect Starbucks robot? Wow! Just wow! I took my previous Einstein comment back, sorry Albert!

Andrew Norville : Awesome!! ........ thank you Sir Neil, for de-glamorizing the ideas of space expansion for our species. Space is not to be taken lightly. Also, thank you for demonstrating the fact that our entire civilization is stuck in a 'monetary, profit driven existence'. There needs to be a paridigm shift in the way we view ourselves BEFORE we can colonize any other planet. Failure to do this will result in failure wherever we go. We only have to look at the way Bees' or Ants' structure and function in their societies to understand the importance of thinking as a SPECIE. I understand human nature is far more complex but, we HAVE TO subscribe to the idea of 'the-good-of-the-species' first. There are so many delusions we subscribe to wholeheartedly without much such ( as you mentioned ) the creation of 'artificial borders' and 'nation-creation'. i'll go further and name the social concept of 'Morality' as another!! ( smiles ) Yet... the idea of seeing ourselves as inhabitants of a planet with resources we should all benefit from.... is considered Utopian fantasy!! ( Let me not get started on the need for individuals to consider personal responsibility for the planet's welfare ) The human race is a work-in-progress, whether or not we survive will require very different thinking about ourselves and our place in the universe. Perhaps this desire to colonize elsewhere will force us to re-evaluate the way we see ourselves. Unfortunately, we change ever so slowly.... and usually it takes catastrophe to prod us along.
