Fascinating. You don't address any of the arguments in the article, and yet you seem to believe that your comment is some sort of refutation!

"Human ingenuity will always find a way," is a religious statement, not a scientific argument. And I hate to break it to you, but it is absolutely not so.

How long have humans been been looking for immortality? Thousands of years. In the 60s and 70s, everyone was sure that immortality was right around the corner. It didn't happen. All the writers who were talking about it have died.

In the 60s and 70s, people were sure that we would have settlements on the Moon almost immediately and on other planets within a few decades. What actually happened is very little.

People are all cheering now because we're repeating the same rocket flights we did in the 60s, but now with a billionaire aboard.

Look at humans today. We're unwilling to spend the trillions it would take not to destroy our planet.

Why would we spend the quadrillions it would take to send people to the stars when it would have absolutely no payoff for anyone living on Earth?
