The crazy speed at which computers were becoming obsolete in the 90s has already slowed down. An decent 5-year-old PC with a good card will play most games made today, even if the graphics won’t look as good as something brand new. Whereas 1999 machines were junk by early 2000. So overall I think the progress in that respect will slow down a bit, even though we’ll soon be counting RAM in TB, just like we went from Spectrum’s 32b to Amiga’s 512 and the mind-blowing 8MB first Pentiums. Today you even want your new laptop to have 2GB, and wouldn’t even look at anything under 1GB.
I think that roll-up screens and keyboards will become the norm, and PCs will thus become ever more mobile, flexible, light-weight and even shock and water resistant. You’ll be able to fold them into your back pocket, or have tiny lasers that can project the screen on any flat surface (and there’s a similar technology for the keyboard). HDDs are already smaller than wallets, and you can even fit a decent 256GB on a USB flash drive.
VR has improved and there are endless possibilities there which have never been fully explored due to limited interest (ie funds).
The technology is here already, it’s just a question of making it accessible.
