First we had toothbrushes... cheap and effective... then we got expensive little power tools that did the same thing... but NOW we have AI! So you can buy a smart toothbrush! And these can cost up to $300... what does it do? Well, it still cleans your teeth... it has multiple speeds/vibrations, etc... and also warns you when you re not cleaning your teeth properly... and sends a report on your performance to an app on your phone... (this is all true)...
Next up, there ll probably be a machine that cleans your teeth for you... and finally, we ll all have smart teeth that clean themselves. Now THAT is going to be MASSIVELY expensive...
