"What are tech companies?"

The author never answers this question. He suggests that small groups of people run them but he does not elucidate what are tech compaines.

If a so-called "tech" company is not profitable, and this may comprise the vast majority of them, then the "engineer salary" comes from VC money. Essentially, a loan. The author omits this simple truth as well.
