Teacher here. No professional affiliation with PCs, Linux or self-hosting. Started out with a Synology NAS and got my first experiences with Linux, CLI, Docker, etc. Switched to Unraid last fall and I self-host quite a lot of services now. 100% self-taught.
Next question would be:
Who pays for disposal and dismantling old nuclear power plants? Might also be relevant for @Eximius@lemmy.world claim. I guess it‘ll be the tax payer. And then we might have a different answer to the question of financial sense.
Privatizing gains and collectivizing costs still seems to be en vogue.
