Neil deGrasse Tyson doubts humans will ever walk on Mars

This is quite a bold assumption. Ever/Never is a very long period of time. ...

This isn't something Tyson ever said.  If you read the article, you'll see that he questions how long it will take and when it will happen.  He never said that he doubts humans would ever walk on Mars.

That part about "ever" is just a horribly-inaccurate headline put on the article by an editor at Wired.  And, for some reason, this thread title followed that inaccurate headline.

Can we fix the thread title?  It really slanders Tyson.

Fair.

He's missing that this is not going to be driven by the old factors.. .instead, it's going to be driven by... manifest destiny, for want of a better word. These billionaires are gambling that they will be a forcing function that forces the economics to happen. If they're right, if it works... it's going to be spectacular. They're betting on the New World, writ large.

If it fails it will be a spectacular crater.

Even manifest destiny still needs $$$ for it to be viable.  ;)

This astronaut says we're not ready for Mars

Tech Insider

Published on May 5, 2017
In an upcoming BBC program, Stephen Hawking has a new message for humanity: Get off Earth within the next 100 years or perish. In order to survive as a species, humans must colonize other planets.

But Canadian astronaut Chris Hadfield has previously said that humans just aren't ready to live on other worlds. In 2015, he visited Business Insider to discuss his thoughts on where humans will go next and why.

Hadfield became a mainstream figure thanks to his YouTube videos from space and wide social media presence. Now retired, Hadfield is the best-selling author of "An Astronaut's Guide to Life on Earth."

I take from this the following:

1) He applauds the desire to go.

2) He is sceptical about the ways and timelines proposed.

3) He doesn't think the drivers of national strategy ("war") and commerce ("economics") are sufficient.

Point 1) shows he supports the general; idea. Point 2) is that he is sceptical of some of the ways and time lines, which is reasonable.  Most of us are sceptical of at least some of the ways and timelines proposed to date! Point 3 is that he is sceptical that the two big drivers of large scale space endeavours past and present are sufficient.  Based on what we currently know he has a point regarding settling Mars, though perhaps not with respect to exploration and science.

This! ^^^^ The title of this thread/that article is pretty inaccurate.

The thing no one seems to have picked up on is NdGT talking about "the money" being the main obstacle to Mars colony and then segueing onto that he thinks the world's first trillioniare will be an asteroid miner.

It's not an unconnected point IMO.  He's implying that the first Mars colony will be funded through asteroid mining.

As of today there are ~4500 NEOs for which it is easier than Mars to make return trips, so I think he's probably right to be honest.
