Those "years of gloom" (which aren't very many years -- has everyone forgotten when the tech industry was widely seen in optimistic terms?) have been brought on by the behavior of the tech industry itself, in large part because of the misapplication of the idea "move fast and break things" (which is, unless I'm misunderstanding, the very essence of e/acc that this article discusses).
Our industry has been breaking a lot of things that people don't want broken, then tends to shame people for being upset about that. The problem isn't some inherent fear of tech itself, it's a (supportable) fear of the tech industry and what other things it may damage as time goes on.
If the industry wants to assuage these fears, the solution isn't to move even faster and break even more things, it's to start demonstrably acting in a way that doesn't threaten people and the things they hold dear.
