If you can swap between different models without memory they have much less power over you.

The fact they're commoditized means they don't have power.

If you lock into a single model, then you can't see the influence of bias.

If the switching cost of models is high then the problem of AI bias becomes significantly more important.

That's the world we're skating towards with vertical integration of chatbots if chatbots are the one UI to rule them all.
