@gemlog @lupyuen - There's room for more than one "right" answer to most problems. Just be sure to frame the problem.
Even yesterday's PC is unquestionably a better PC than any Pi-like substance. My always-on Pi (3) monitors smokeping, telemetry from several devices, PiHole, and several more tasks. The comparison of electricity consumed by a PC is laughable.
Turns out that "Pi" grew to encompass a few lines: education, hardware hacking, net appliance/server, workstation, etc. Not all are $35.

@gemlog @lupyuen That's the sad thing about Pi5: it misses the mark for ALL of those.
Too expensive for disposable hardware & education. (Pi Zero, Mango Pi, Ox64 hurt less to smoke. Each is < $10. All run something recognizably "Linux".)
Too wimpy for desktop/workstation use.
Not even price OR performance-competitive in its own market for net appliance, as Greeling calls out.
They released a 2020 product in 2023.

@lupyuen A forth and probably morr impactful way that threat actors abuse Discord is by developing it.
"Threat Actors abuse #Discord in three ways: leveraging its content delivery network (CDN) to distribute Malware, modifying the Discord client to steal passwords, and abusing Discord webhooks to steal data"
