The difference is that, to this day, getting a straight answer on what web 3.0 is, is difficult. On the other hand, people are using ChatGPT to write all sorts of emails - cover letters, resignation letters, layoff letters, customer support letters - and that is a use case that those who aren't being willfully blind can immediately grasp as being useful, for people who are in job roles that require a lot of that sort of work.
I think if you produce a novel technology and make it free then people will use it. If you feel confident that these things are "useful" then have people pay for it. Will they still use it for beyond entertainment then?
CoPilot, after an extensive free preview period, garnered something like 400k subscribers at $10/m. I'm curious to see where that number settles at over time. My hunch is that the things you're seeing people use ChatGPT for are more novel than useful and a lot of the value prop is that it's currently free.
To put this in context, GitHub has $1B ARR and roughly 90M active users.
