It’s unfortunate, but you’re falling into the trap of “I don’t like it, so it’s incapable”.
Most big development studios on the platform use AI loads. Through the use of Roblox’s MCP server, AI can see, and understand your game - editing it directly. Pair that with your personalisation instructions, and you can get it to script just as you would. You seem to still believe that AI exists as a separate chatbot like it did when it first came about. It’s not like that anymore.
I for one don’t use AI, I make games for fun, as a hobby.. But I’ve experimented with it w/ MCP, and it is genuinely scary. It can keep up with me fine. Scripting on Roblox is not that difficult, AI can easily write LUAU code more efficiently than most intermediate and beginner developers. It avoids common traps, and cleans up it’s connections, which is an issue most beginner devs aren’t even aware of. For profit studios use it, and you wouldn’t know it. Is it more efficient then what an experienced dev could make? Probably not. Is it more efficient then you and me? Yeah, for sure. Especially when you’re pointing out issues as they arise.
It’s your choice to not use AI, one that I ethically agree with. But you should be aware of it’s abilities, and not just write it off as “slop”, especially if you ever want to take Roblox seriously as a career.
When someone who knows what they’re doing uses AI for scripting, you can’t tell that they’re using AI. The amount of times I’ve seen the generic claude UI in popular games is nuts. It is quite literally like having a developer, that is much quicker than you, and abides by your every command.
Is it good enough to fully replace scripters at the moment of time? No. For more complex, niche, gameplay mechanics, you’ll still need to finetune it yourself. For the best results, you need to use the correct terminology. If you’re not a scripter, and you just ask it to “make me a fully fledged FPS game” - it’ll make slop.
If you can afford it, I would recommend picking up a claude subscription for a month - just to see what it can do, not to use it on your projects. Be aware of technological progress, don’t just shield your ears and go “well, it’ll never beat me!”, that’s how you get left behind.
