Tech? like technology? What does it mean? Because surely companies that apply scientific knowledge for practical purposes aren't 'bursting' all over the place, right? Does it refer to specifically these huge companies quoted on the article?
You know exactly what it means. There is no way that you think tech in this context means "applying scientific knowledge for practical purposes" unless you have - and I truly, deeply mean this with zero disrespect whatsoever - weapons-grade autism.
When did it become the cool thing to pretend to not know anything about the context in which a particular discussion happens? It's maddening, but also completely exhausting.
