People are already deploying tools like Anubis[1] or go-away[2] to cope with the insane load that bots put on their server infrastructure. This is an arms race. In the end, the users lose.
E.g. if I'm the developer of a workforce management app (e.g. https://WhenIWork.com) I could deploy BLAST to quickly provide automation for users of my app.
I think it would take more substantiation to claim this. Maybe 10 out of 1000 websites will get closed, but the users will be able to use AI tools to use the remaining 990. Not sure about you, but sounds like a win for users to me.
this may be true for the time being (or not), but will sure change if/when more [websites] become aware of what is going on. The result will be 10 out of 1000 websites will remain open, and not the ones you actually want. The more pressure there is on the sites/servers, the more these will have to act to stay online to begin with.
A few vocal people on HN barely scratch the surface.
