I think fundamentally it's a combination of 1) arrogance in thinking they understand how the world works socially (and are very capable of solving problems that are fundamentally social), and 2) a complete lack of understanding of how the world works socially.

People hate them because at best they're idiots who achieve nothing and at worst their hardworking idiocy makes the world materially worse.

In particular, techbros tend to have a belief that social problems can be solved with technological solutions (e.g. the solution to the housing crisis is to design a construction technique with lower material/labor costs). The problem in this instance is that if they asked themselves "what is the root cause of the problem", instead of jumping straight into the technology (they commonly "disrupt" old technology by ignoring some particular prevailing wisdom, and frame ignoring said wisdom as "not being closed-minded" instead of as "being stupid and ignoring the lessons of the past" - which, to be fair, is occasionally true).

There's also a more explicitly political component, but saying "they have X politics which is stupid" is a great way to start a political flame-war so I think I'll skip that.

So tl;dr: technosolutionism, plus overconfidence on trying to solve social problems that they don't even understand, let alone have the ability to solve.
