I'm thinking of this like car radios. Most cars used to have this standard called DIN to put the radio in. Most cars today don't have DIN mounts anymore. We've gotten way nicer, bigger touch screens in our infotainment now since cars are not locked into one form factor. On the other hand, it sucks in some ways because vendor lock in. I hope we at least get a tradeoff like that - that there will be something in return for it.

There are systems like the NUC but if I want a super-high-end 5090 and top-end CPU, all of the options to cool them feel like... well, something kluged together from whatever parts I can find, not something that's designed as a total system. Maybe we'll get some interesting designs out of this.

I'm afraid the acceptance (and, more troubling, the seeming desire on the part of technical people who I see as misguided) of mobile computers in the smart phone form factor to be locked down and hostile to their owners has moved the Overton window on personal computers being equally owner-hostile. The bucket-of-parts PC ecosystem is less susceptible to an effort to lock down the platform and create walled gardens. If that market goes away it gets easier to turn all of our personal computers into simply computer-shaped devices (like Chromebooks and iPads).

I'm really fearful that PCs are going down the road of locked bootloaders, running the user-facing OSs inside bare-metal hypervisors that "protect" the hardware from the owner, etc.

I'll accept that I'm likely under the influence of a bit of paranoia, too.

I'm strongly of the opinion several unaffiliated factions (oligarchs, cultural authoritarians, "intellectual property" maximalists, software-as-a-service providers, and intelligence agencies, to name a few) see unregulated general purpose computers in the hands of the public as dangerous.

I don't think there's an overt conspiracy to remove computing from the hands of the public. The process is happening because of an unrelated confluence of goals.

I don't see anybody even remotely comparable in lobbying power standing up for owner's rights, either.
