I think you might be on a path of discovering the whole truth, what you've written here I recognise as on route to the whole truth, but until then, ego might be getting in the way, I don't meant that to sound insulting, we all had to have egos, like the tech bros.

I bet if I said to you in the future we would be fixing the planet by doing things like producing small carbon fibre maybe supersonic, concorde-like aircraft that could fly fruit alone from places that grow it, to places that don't, you would say I am barmy, but it's the truth, that even maybe most of the tech bros can't see yet either, definitely not Musk, who has dismissed hydrogen as "Stupid", for example.
