Interesting notion, and one I agree with. Even if you don't look at data, statistics and all the other mumbo jumbo, one may divine a steady climb in technological advancements in every field just by shorthand glance.
However, one thing I believe must be taken into account is human need and desire. We create new technologies, new advancements and new solutions because human beings need and want that which is better than they already have. Dad often mentions about how the first hard drives were about the size of a very large plate, but which were only capable of storing ten megabytes worth of data. Fast forward to today, and you have SSDs that are barely about the length of one's hand without any easily-damaged moving parts in them, but which can store up to four terrabytes worth of data with relative ease, and can start up in a fraction of the time the humble hard drive would take.
This was fueled purely by need and desire (for more digital space), and because of the consumerism element of trade in today's world, the most cutting edge tech is often only the privilege of the extremely wealthy (or at least those averagely well to do), and such advancements only become more freely available to the tiers of society below once they start to look more outdated compared to their newer counterparts. Still a privilege, but also kinda depressing at times lol.
So yeah, I'd say the drivetrain behind Moore's law is directly connected to the increase in human numbers in recent decades, and the ever present need humankind has; to want what they do not already have.
Guess it's as much of a boon as it can prove a curse at times, eh? :P
Anyway, cool post, and thanks for sharing it :)
Cheers :D
