Look at what happens today when people try to stretch the current limits: Musk test launches the largest rocket known to man and it (expectedly) fails. Even the folks around here start Pooh Pooh the man and the process.
There is no way I would test anything in public these days. The world expects perfection, every time, all the time—and the people setting those expectations have mostly never accomplished anything on their own. Who needs that?
The dreamers and the engineers ARE out there. They just fail in private these days.
Amen, brother!
