Looking at what's happening with RAM pricing and Crucial being shuttered, the doomer in me thinks they could just pull the same thing with every other PC component. It's not like some plucky band of upstarts can start 3D printing organic free-range FOSS processors, hard drives and motherboards in their garage- all of this shit comes out of a couple of giant plants in Asia. If porky strangles the supply, that's it. In the end all the average joe schmoe will be left with are cloud-based terminals that rely entirely on subscription services and that require strong identification to even use (and that will monitor and log every single fucking thing you do while drowning you in ads)
Wanna install Linux? Go ahead! What are you going to install it on though, your grandpa's old Pentium?

Rent-seeking is always what capitalists want to do so my tinfoil hat theory is that big companies want to rent cloud computing capacity to the general public. I think about it more in gaming where there already existing cloud streaming services.
