I’m surprised this wasn’t mentioned in the keynote or State of the Union, but Apple’s model training data is either licensed or publicly available on the Internet. No personal information is used.
I don’t think it’s as ethically sound as the author thinks, but it’s worth a discussion at least.
“Publicly available on the internet” is very wishy-washy. Just because something is publicized on the internet, does not mean you have the rights to use it. I hate how companies constantly get protected through draconian copyright laws but your average Joe is just content to be used to make even more money.
