I don't necessarily think that is a stop-gap against people socializing more offline/being socially productive online.
Especially considering the fact that it seems more the case that the bigger stop-gap is what we already have:
In asian (especially Japan) it's host(ess) clubs.
Globally for friends it's influencers exploiting loneliness.
Those are things I think has to go for people to embrace offline socialization or using their online time better.
It's a bit of a complicated topic in general.
Personally I think ai code should always be open source to at least make it the most "ethical", others can see and edit it as they see fit.
Generally though I've noticed that the spirit of open source (community owned code) has slowly been morphing into a few pointers that in some way undermine open source, whenever that be the fact that folks get more entitled towards open source projects or that they see certain open source licenses (specifically GPL) as a tool to build an anti-capitalist moat.
Despite the fact that almost every open source or accepted open source license by OSI or FSF explicitly states no warranty and commercialization of said project is allowed, just that most people don't contribute money let alone code (just look at the xz debacle even now the dev is not given sufficient attention in terms of commercial and social support to maintain it).
To be fair to Carmack, his vision of open source is one shared by a lot of the "free means anarcho-free" developer camp and as such if said code is used in ai or to bomb children then so be it.
I guess this is one of the major tension of open source is exactly what open source ought to be:
A drive towards ethical code or a drive towards anarcho-free, because stating "free as in freedom" is too vague; freedom has the connotation of both the idea of freedom TO DO something and the freedom to be EXEMPT from something.
In the end I believe that freedom to be exempt is more important than the freedom to do.
Due to the fact that the bad actors usually benefit more to exploit freedom-to than freedom-from, hence why beyond community building the (A|L)GPL helps out in ensuring both as a user but also as a developer that the code written is protecting us both.
Whenever or not AI is part of that is well going back to my point that ai code should most likely almost always be open-sourced if one wants to "lift the burden".
