Machine learning is a form of AI. It’s the most useful one for complex problems we have right now, that’s why everybody is using it. The only reason we used random forests and more bespoke algorithms so long is that we didn’t have the compute power or infrastructure to train these networks on a mass scale. ML was invented decades ago but extremely unpractical because computers struggled to do any kind of efficient calculation the moment you added a decimal somewhere.

The kind of AI you find in Google Maps route finding just isn’t very interesting, because we’ve had that for decades.
