It seems like as hardware gets cheaper, software gets more bloated to compensate. Or maybe it’s vice versa.

I wonder if there’s a computer science law about this. This could be my chance!

Is your name Wirth?

Sorry to burst your bubble:

Not exactly the same (it's about power rather than price). But close enough that when you said it, I thought, "oh! there is something like that." There's also more fundamental economics laws at play for supply and demand of a resource / efficiencies at scale / etc. Given our ever increasing demand of compute compared increasing supply (cheaper more powerful compute), I expect the supply will bottleneck before the demand does.
