The first computers cost millions of dollars and filled entire rooms to accomplish what we would now consider simple computational tasks. That same computing power now fits into the width of a finger nail. I don’t get how technologists balk at the cost of experimental tech or assume current tech will run at the same efficiency for decades to come and melt the planet into a puddle.
AGI won’t happen until you can fit enough compute that’d take several data center’s worth of compute into a brain sized vessel. So the thing can move around process the world in real time. This is all going to take some time to say the least. Progress is progress.
