The rate of technological change is faaaaaaaaaaaaaaar slower than people think. For example, automobile travel and roads have not changed significantly since the 1960s. Air traffic control is still done by voice over noisy channels. Clothing is still sewn by Asian ladies on the same sewing machines as 1960. Airplanes are not much different than the 707, nor faster. Houses are still built from wood sticks and gypsum, 3D printing notwithstanding. Trains still run on steel track, same as 1850, though at higher speeds in a few countries.
The only significant changes have been in electronics and consequently everything digital.
Hey look everybody, some one has discovered the fact that economics and efficiency eventually plateau's. Automobile technology has changed dramatically since the 1960's, tire technology, braking, sensor, controls technology has been making improvements year over year. Or do you still adjust the points on your car, do you add tetraethyl lead to give you that high compression ratio or adjust the choke on those cold winter mornings? BEVs using lithium-ion have become fairly widespread as well. You think that steel track is manufactured the same way it was back in 1850? Or perhaps you have a job as the chief stoker on the locomotive. After the Concord failed in the 70's there's been no real need to move airplanes faster.
Yes general AI will change everything. I doubt it will exist during the lifetime of anyone who might read this.
640k should be enough for anybody. Or perhaps, no wireless, less space than Nomad, lame.
