First on the "scalable": CS is most definitely scalable, the question is how much. Without using any tooling whatsoever I dare say it scales in O(N*(log N)^2). I can understand the will to optimize it, and with good tooling, I have no doubt it can become sub-linear, which is more than enough. Anything sub-linear wins money with growth, so no need to "make it a product" (which I read as: Put a team of O(1) to replace those people, but maybe I'm misunderstanding)
Anyway on to my point: Your Google example proves TFA's point: Google having broken CS is one of the major pain point against Google most people here have. Another Google pain point can probably be explained by misuse of KPIs: Google products that keep getting killed, and replaced, again and again.
Even the best people are subject to "the spreadsheet mentality". Even when they are aware of it! My employer's founder bought back the company to stop focusing on the company's share price. Musk would like to take Tesla private. France renationalized EDF which was already >80% own by the state. etc.
