I first got exposed to the problem from this Adam Conover interview with Dan Olson: https://m.youtube.com/watch?v=4aU-QkJfgGw

This article is also a nice encapsulation of the problem, even though it focuses on financial technology only, it applies to other tech companies as well:

In an attempt to reboot the global economy, central banks slashed interest rates to almost zero, resulting in an era of cheap money.

This resulted in two things. First, it incentivized investors to fund promising (and, in many cases, not so promising) young tech companies. But it also allowed for the emergence of business models that, in any other circumstance, would be completely unviable.
