I think with this way of thinking there will never be progress. It's thanks to this try-and-fail that this man was able to build things that nobody thought to be feasible. We are talking about mistakes that were done in the '80s, meaning that this man is trying to leverage what we have nowadays and he still can't, which is pretty sad, considering how advanced we think of ourselves compared to 40 years ago.
Sometimes it's this way of thinking that really prevents innovation: we tried, it didn't work. Sure, you tried under different circumstances, I am quite sure you gave up on that for whatever reason and you are fine with it. Good lesson. However, there will be a new generation that will make it, no matter all your "I told you so".
I want to see if in the future, when we'll have highly developed AIs, we will think "oh, 200 years ago we tried already and it didn't work".
