If I had to, I guess I'd pay $100/month for ChatGPT.
But I also don't see how these things don't keep getting cheaper. What recent technology has gotten more expensive over time?
Cloud. And AI is not very different from the fundamentals of Cloud; there's vendor lock-in, meaning the vendors can raise prices at will, representing a liability to whoever tries to depend on them.
There’s short-term increases sure but there’s no doubt in my mind that $100 in cloud today gets you much more than $100 in cloud 10 years ago. And the $100 is worth less today!
