Hardware and software backdoors does scale.

Data exfiltration through audio / fan speed / LEDs blinking / power draw / etc. simply doesn't.

I think that a discussion about metric shitloads of networking gear being compromised is not the place to make fun of the few that didn't compromise on security.

There's a place for offline/airgapped devices and private keys (PGP keys, seeds, whatever) being generated by throwing dice.

If anything all these backdoors do show that math/cryptography do work. The NSA's budget may be 100% of the US GDP, they still wouldn't be changing Sun's gravity or the math behind cryptography.

The joke today is on those who kept making fun of those who didn't trade security for convenience.

Both these computers were fan-less, like nearly all hobby computers at the time (clockspeeds were single digit Mhz). The Amiga only had a floppy disk drive.
