Unpopular opinion: the reverse. God created men, but Sam {Colt, Altman} made them equal. Commoditizing physical or intellectual power makes them more accessible to lower classes, and keeping them more expensive protects class privilege.
How does it help equalise, if the commodity is sold "at market value" by the richest, and all intellectual input is immediately fed back into the tool. Looks at best like a weapon to supress
Imagine two bright high school students. One goes to a tony private school taught by people with PhDs; the other is in a developing country. They both want to understand, say, Morse theory. In a world without AI, only the former has access to knowledge about it. In a world with AI, the kid in a developing country can access the knowledge roughly as easily. Even if they were paying for tokens, but free tier models provide an absolute equality.
How do we know free tier models will continue to provide adequate services? They are pretty good right now, but only because all big players are happy to burn enormous amounts of money.
You're not alone in this line of thinking. While "AI" has its perils, it strikes a nerve on people who previously felt comfortable in their jobs. Worrying about AI is a privileged position, while poorer people cannot afford the luxury to do so.
