The problem is that undermining artists by dispersing open source AI to everyone, without having a fundamental change in copyright law that removes power from the corporations as well as individual artists, and a fundamental change in labour law, wealth distribution, and literally everything else, just screws artists over. Proceeding with open source AI, without any other plans or even a realistic path to a complete change in our social and economic structure, is basically just saying "yeah, we'll sort out the problems later, but right now we're entitled to do whatever we want, and fuck everybody else". And that is the tech bro mindset, and the fossil fuel industry, and so, so many others.
AI should be regulated into oblivion until such a time as our social and economic structures can handle it, ie, when all the power and wealth has been redistributed away from the 1% and evenly into the hands of everyone. Open source AI will not change the power that corporations hold. We know this because open source software hasn't meaningfully changed the power they hold.
I'm also sick of the excuse that AI helps people express themselves, like artistic expression has always been behind some impenetrable wall, with some gatekeeper only allowing a chosen few access. Every single artist had to work incredibly hard to learn the skill. It's not some innate talent that is gifted to a lucky few. It takes hard work and dedication, just like any other skill. Nothing has ever stopped anyone learning that except the willingness to put the effort in. I don't think people who tried one doodle and gave up because it was hard are a justifiable reason to destroy workers' livelihoods.
