Software moves "slower" because hardware needs to exist 1st and needs to see a widespread adoption in order to justify the cost of development and continuous improvement, also only hardware companies have the expertise because, well, they are the ones who developed the thing.
Doing software actually costs a lot, and no one wants to spend that kind of money past the "good-enough" threshold if they don't have to.
Software then moves a lot slower, because most user applications are pretty bad at using more than one core efficiently; and these CPUs have been mainstream for some 15 years now.
The hardware is certainly much more capable than what little use the software tends to make of it.
