We could start by not requiring new chips every few years.
For 90% of the users, there hasn’t been any actual gain within the last 5-10 years. Older computers work perfectly fine, but artificial slow downs and bad software cause laptops to feel sluggish for most users.
Phones haven’t really advanced either. But apps and OSes are too bloated, hardware impossible to repair, so a new phone it is.
Every device nowadays needs wifi and AI for some reason, so of course a new dishwasher has more computing power than an early Cray, even though nothing of that is ever used.
And that’s mostly the “bullshit IoT” category. It’s not like the demand for phones and laptops exploded in the last years, it’s IoT, AI and other useless crap - regardless of the process node.
