Also, there's the fact that recreating large software projects still will require highly skilled labor which will be thoroughly out of reach of the future's vide-native coders, reducing the likelihood of competition to come up.
At the bottom of things, the problem we are facing is not a technical, but a societal one. Our societies are rapidly regressing to "techno-feudalism" (see [1]).
There will be some tech-lords in their high castles. Some guilds with highly-skilled engineers that support the tech-lords, but still highly-dependent on them to maintain their relative benefits. And then and endless mass of very-low skilled, disposable neo-peasants.
AI needs regulation not to avoid Skynet from happening (although we should keep an eye for that too), but because this societal regression is imminent.
