People need to remember in this, our first-world country alone, there are around 3 million people who don't use the internet. Worldwide there are billions.
Plus, AI is primarily learning (so far at least) from the internet - which is pretty crap. So it's going to have a warped, stereotypical, somewhat nasty idea of what human culture is that is very 21st century timebound. Yet my great-grandmother was born in 1888, she was a Victorian. Her influence in my family remains strong, and it's probably the same for many people. So AI misses all that and will be slightly off-key.
Another issue is, it's very discernibly American. Ask it to write something persuasive and it's so wrong for UK or French culture for example.
Don't believe all the hype (which comes from the people who expect to profit from it). Think of it as a spreadsheet on steroids. It might be great for crunching data, but ask it for something humanities based and it just echoes the most typical pop culture - just like all the other pop culture.
What worries me is is its ability to falsify video and photos - media we've been used to thinking of as irrefutable.
We do need to shift our thinking, but also not get too excited over the changes it will wrought. It's just more tech, a machine, like mobile phones which I think a lot of people are getting very bored of now.
People getting together, changing the way they live and interact with each other and the world, now that's exciting.
