It did, but I do not see this as an unbreakable law and I believe that the rate is slowing and will continue to decline.
Technology is slowing down and will continue to slow down because today we have alternative priorities and are ruled by corrupt morons.
Disagree entirely on technology slowing down.
Humans only went to the moon because of the space race--the forces of capitalist US and communist Russia were vying to prove to the world that they were supreme.
So we spent a shitload of money on something that had no intrinsic economic value... A tourist trip. Vacation, as it were, to the moon.
Note that sending things [satellites] into space is of big commercial value. It's of enough value that it's a for-profit business.
Sending people into space? Not so much. Maybe eventually.
Radical life extension is a much different prospect. How much would you pay to halt/reverse aging? How much would you pay to be in the prime of health perpetually? To not wake up with random things hurting because you're on the wrong side of 40? To feel as young and strong and wonderful as you did ever day at the age of say 25-30, to have that metabolism, to have that vigor?
There's a huge economic opportunity available to anyone who figures this out.
