Interesting comment, because according to https://en.wikipedia.org/wiki/PDP-7 the PDP7 (the first computer "UNIX" ran on) had ~9.2KB of memory (supporting up to 144KB).
Most contemporary SoCs will have more memory (and compute power) than that.
That's a complete non sequitur. Just because UNIX can run on lower end hardware doesn't mean "a full UNIX computer" is the best tool for the job.
