It can scale, humans can't.

One human needs to teach one AI system how to do one specific task. Everyone can now use this. Before you had to teach every single human having to do this task and the next generation.

You can easily gather a group of humans and teach them all at once. Humans learn and generalize far more effectively than an AI, we have millions of years of evolution working in our favor here. Will AI match us at this one day? Maybe, but it's certainly not today.
