I've been around since Bubble 1.0; I started working in San Francisco in 1997. The thing I find horrifying about this article is the way Vision Critical apparently takes the worst aspects of startups and amplifies them, while taking the best aspects and perverting them.
As example, I was an early Agile person; I went to the main US Agile conferences 2001 to 2008 or so. The whole point of things like sprints and standups was to control schedule pressure and keep our work lives sane. The point of agility was not to increase risk and fear, but to make it safe to take risks so that we could be both bold and serene. If you had focused on "maximizing productivity", you would have received stern talkings-to about "outcome, not output." The point was not to put on a show of working hard; it was to radically increase effectiveness.
The sales-bro culture of competition and aggression is also nightmarish to me. It's inevitably short-sighted. I'm sure it works to generate rapid growth, but at what cost to the people and the long-term prospects of the company? It's a sign to me that they definitely aren't changing the world, but instead are likely pushing a mediocre-or-worse product on the world. As if that's new.
For what it's worth, I have the impression that this sort of awfulness is is more common in tech startups that aren't in SF/SV. I take it as classic cargo culting: instead of adopting the important parts, they adopt the visible parts. So maybe some of the saltiness here is just where people are working.
