Kaze Emanuar has done so much great work in optimizing Mario 64's engine over the years (check out his YouTube videos, they're fantastic) but guys like him are such an anomaly, I'm fine if robots are breathing new life into retro games and empowering consumers to be able to play these games in more ways instead of paying the IP holder every ~7 years to play a (likely lazy) port of a game they already own on a new system.
I think the people who are relying upon AI the most, might not contribute to OSS anyway. I can certainly say I am in that boat because I do not have software development skills and I do not want to learn how to do it. However I am very much using AI to write alternatives to some software I use like Kodi, because I can have something bespoke to my needs and perform "better" in terms of metrics that I care about, which may not align with metrics the contributors care about.
Have you tried making a skin for Kodi? Awful experience, poorly documented, and something only a handful of the community can do. They tend to perform poorly because of an over dependence on python plugins, have many foot guns, and can feel sluggish and unresponsive. But I can say make me a media player that looks like Netfix and pulls trending from trakt, and in one shot have something working on Android TV that performs far better for me.
There maybe arguments that AI couldn't have done that without OSS like Kodi to train on but I dont think thats accurate.
A huge reason for that is the knee-jerk reaction of some communities (gaming especially, for some weird reason) at AI usage. So people build for an audience of one (maybe sharing with their closed friend group), and move on with their lives.
In the US at least, the gaming industry as a mismanaged trash fire. Workers are underpaid and unemployment is high. Executives are regularly shuttering studios responsible for highly acclaimed games and touting AI as the solution to all the problems. Given this framing, the way to support the studio making your favorite games is to make it clear that you don't want to replace everyone with AI. In fact, no AI use at all. It's one extreme in response to another.
From a hobbiest perspective, it's not great either. Translation projects that have been in the works for years have gotten beat to the punch by (extremely shoddy) AI projects helmed by people who don't speak the language they're supposedly translating. In one recent case, a half-completed human translation was stolen, finished with AI, and presented as an original work. Decompilation projects have had similar issues; AI use isn't disclosed until people start discovering that the result isn't accurate to the original.
Ah, yes. Thank goodness the FOSS community never generated many different tools for the one purpose before, right? \s
