AI wasn't the "next big thing" ... the market has missed it. Maybe it's not obviously profitable enough. But, there are ideas out there growing that will change the world and only the people close to them even know what they are.

It's not totally possible to just decide that something is going to "change the world." You can fake it for a bit, but eventually reality sets in.

That doesn't mean that nothing is happing. You just might need to listen in different places.
