> What's your definition of affordable? What years were PCs affordable?
That DIY entry PCs can be built for 400 USD or less. Budget PC should be able to browse net and play a few games on the iGPU (so overall 1TB SSD, some iGPU and 16 GB of RAM). Ideally on current generation of RAM and processors.
> By my reckoning PCs are affordable today. If you're not trying to run games they're downright cheap.
By what reckoning? And not just games, 3D workload, compilation. Hell. Even browsing + some productivity eats 32G of RAM as if it were nothing.
> I'm not sure what issue you're referring to with bitcoin
The first permanent jump in GPU prices. After Bitcoin prices of high-end GPUs remained at +1000 USD.
> Cartels just agree not to make anything for PCs? Why would that happen?
For bigger profits. You can see most hardware manufacturers moving from selling to consumers to selling to governments, cloud, and data-centers.
Why not make anything for PCs? Because individuals can't compete with the coffers of large corporations and governments.
> The point of restricting supply to a market is to maximize profits, not to refuse forever and lose out.
You can maximize profit by leaving a market. In the same way, you can still sell SSDs but for much bigger margins to data centers and governments.
Say all but one/two manufacturers leave the consumer market. The monopoly/duopoly hikes up prices again and again until you have a few stragglers on 40k USD workstations, and everyone else is on an iOS-like platform.
Once you are in the walled-in-cloud-garden, computer is not your own, and you can be monitored perfectly. This is something most governments want and is essentially the endgame for war on general computing.
