HN is mostly people trying to get rich selling themselves to VCs, so I'm not convinced that this is where the spirit of "hacker" is kept alive.
Yes, some are trying to sell themselves, which may be distasteful to you but people need to eat.
Others are activists, pushing their views.
Others here are just reading and occasionally commenting, like myself.
But there are also a lot of very passionate and smart people here who are pushing boundaries and limits with what they can do in terms of hardware and software.
