I'm sorry but this is just BS. Raspberry Pi are not garbage.

With good software, and by that I don't mean barely tested Java or Nodejs HomeKit wannabe services, Pis are rock solid.

I'm into SDR (software defined radio.) I have written software which processes 8MB of samples per second, and runs for months without reboot. It means 90-100% CPU load, 100% of the time.

Oh, and the same Pi also hosts AirPlay server and manages ~10 Arduino devices in spare cycles.

Bad software can make any device useless.
