That's what they once said about walking on the moon.

More seriously though, just because many projects were wrongly considered foolish in the past, does not mean one can not point at a new one and call it foolish. History tends to remember those who turned out to be brilliant, and forget all those who genuinely were foolish.
The example I like is Franz Reichelt [1]. People around him were watching as he prepared to meet his death. Nobody said "don't do that, you'll kill yourself". Why? I guess because they were not sure, and they did not want to be the person who dissed someone who might be remembered as say the Wright brothers were.
I guess I'm not comfortable being the guy who says nothing as he watches people being foolish or delusional.
OK, that one guy was foolish he should have started small and worked his way up. Perhaps a death defying leap onto a mattress, would have been better. But there are plenty of others who were close to a variety of successes and them not succeeding doesn't mean they were foolish.
There must have been hundreds or thousands of potential aviators, but we remember the brothers at Kittyhawk because of their success. This doesn't make the others fools, likely they were successful in some of their other plans or iterated on designs more like the flyer afterwards. From all of their perspectives as long as they minimized danger, unlike Franz, they would live to see another day and keep attempting High risk High reward situations.
This is much the same with startups today. Plenty made their fortunes in tech startups and while history might call all but a few failures, many are relaxing with their millions or even just comfortable enjoying their backup plan of a high tech job and settling down with a family.
