[I literally had this thought in the shower this morning so please don’t gatekeep me lol.]
If AI was something everyone wanted or needed, it wouldn’t be constantly shoved your face by every product. People would just use it.
Imagine if printers were new and every piece of software was like “Hey, I can put this on paper for you” every time you typed a word. That would be insane. Printing is a need, and when you need to print, you just print.
At the time computers were totally useless for everyone but big firms, banks and military. Ads for computers were rare and confined in specialized magazines. For mundane people, computers started to be actually useful (like money earning useful) 20 years latter at least. That’s how I understand your approximative comparison
