Tech companies respond to incentives. If the technology exists to create and sell devices that are useful to people and legal, then they'll do it, and people will buy and use them. And that is fantastic - I'm great with tech companies making tools that makes my life easier. I absolutely plan on using the heck out of the next wave of AR glasses for digitizing historical documents so I can have both hands free instad of holding a phone in one. Better audio recording devices? Yes, please.

Simultaneously - I own my words, either written or spoken. This isn't really all that different from copyright, and I'm rather surprised we don't more regularly bring that reasoning to bear on this issue. If I give them to you in a private conversation, then those words are for you to hear. If you record them without my consent, then you're violating my (copy)right. If a company takes those words without my consent, then that company is violating my copyright.

I don't know exactly what should happen to people and companies violating my copyright, but I do remember when it was the other way around a few years back and the RIAA was getting people fined thousands to tens of thousands of dollars per incident. That seems about right.

The AI tech companies already violated perhaps millions of copyrights.

They should have quite a hefty fine to pay.
