I believe in the 80-20 rule.

Getting to 80% of image synthesis takes 5 years, but the last 20% will take another 20 years.

Similarly with text, voice and video. So for the near future, I will prefer human output to machine output, but that is going to change eventually.

If 90% of content will be AI-generated by 2026, then that content will be crappy. Not to say that human content is good.
