For now. The technology will be ready and efficient in 200 or 300 years. Humans are pretending it's 2400 AD. It obviously isn't. There won't be a trip to Mars, there won't be EVs that work, there will never be an elimination of fuel usage in anyone's lifetimes currently alive. Hell, we can't even functionally control an economy or borders amidst moronic economics and left wing politics. Keep it simple, stupid is a quote I like to remember. We're playing fantasy fiction without the technology and people are getting less intelligent as time passes due to smartphone addiction. We will all be dead and long gone as even a 1 month old alive now will be as well before any of the pipe dreams we read about will be a thing. I feel bad for Elon Musk and other tech people because they are trying to build things that there simply isn't ability to do so yet. Just live for now. Soon it will be over and you'll not even know a thing. Dead, gone, ashes or a rotting corpse.
