There will always be naysayers around to argue against advancement. The arguments against the possibility of manned flight in 1903 were the same arguments against manned space flight in the 1960's, and that sending moving pictures through the air was a joke by some lunatic with more money than brains. And that supersonic flight would never happen. And computers would never be in every person's pocket.
Those same doubters said that Elon Musk would never succeed in launching a satellite into orbit and then having the launch rocket return and land on a barge in the ocean. And they doubt there will ever be electric powered semi trucks. Keep doubting if that's what makes you happy, but denying the inevitability of progress has been and always will be a fool's errand.
My 2¢, and nothing more.
