Earlier quoted context omitted.
A "non-technical person" is someone who is not skilled in technology, usually IT, not someone who knows nothing about technology. The fact that there exists nobody who knows nothing about technology is a good clue that the term doesn't mean that, or else it'd be a useless term, as you pointed out > people are just “technical” in ways that IT folk don’t recognise. yes, perhaps they can work an abacus, or throw a javel…
OK so you're making my point for me. "Non-technical" is just an IT trope that we should stop using if we're not talking about employees. And indeed, nobody specified that we were talking about employees, much less FAANG employees. The bit about the abacus just underscores what I mean. It's derisive. Consider not using the word "non-technical" until you've grasped this.
the term "non-technical" is used because it is useful (notwithstanding your personal interpretation of it to mean "knows literally nothing about any technology"), so what term do you suggest we IT professionals use which conveys the same information in an equal or shorter length? Consider providing people an alternative they think is better if you personally don't like the language they're using, vs. just feeling upset and complaining.
