Much of the public response to language models like OpenAI’s ChatGPT has focused on all the jobs they appear poised to automate. But behind even the most impressive AI system are people — huge numbers of people labeling data to train it and clarifying data when it gets confused. Only the companies that can afford to buy this data can compete, and those that get it are highly motivated to keep it secret. The result is that, with few exceptions, little is known about the information shaping these systems’ behavior, and even less is known about the people doing the shaping.

Maybe also because of the learning curve. Those who find to bothersome to set up accounts on their preferred instances will just give up and stick to whatever toxic platform they’re currently using. In other words, I’d like to think of fediverse users as smarter than most.
