A decade in computing used to mean revolutionary improvements:

- from the C64 to the Pentium

- from the Playstation 1 to the Xbox360

- from the Nokia 3310 to the iPhone 4.

Each of these in roughly a decade.

But 2015-2025 in terms of desktop PCs? Some decent (but not revolutionary) steps forward with GPUs, and much more affordable+speedy SSDs. But everything else has been pretty small and incremental.

And when enthusiasts upgrade, the old parts usually find new homes. My old 6th-gen i7 from a decade ago still has more than enough power for my Dad to use as a home PC for basic photo editing, web browsing, and spreadsheets. But Win10 end-of-life wants to turn that machine into e-waste.

I think that is normal across most technologies or fields. Progress is an S curve (or series of curves), and it's easy to be amazed when looking at the steep bit. Early on progress is slow due to not much investment and going down lots of dead ends, while later progress faces increased complexity and no low hanging fruit left.

The middle bit is where the disadvantages of the early phase has gone, but the disadvantages of late phase hasn't kicked in yet.
