This would probably cost SE money, which I'd rather see going directly back into the community. Basically the "tangible" benefits I want to see from these partnership are development and staffing rather than access to a tool many users in the community consider a bit of a anathema.
Considering the company's trying to integrate LLMs into their paid product, put in a fairly significant chunk of resources , and... downsized staff - I don't want to see the outcome of the partnership literally being OpenAI selling access to our own work, masticated beyond recognition in return for... well our work.
I also don't see any particular benefit in terms of why I'm on SE. Which tends to be answering interesting problems, and occasionally asking questions about properly befuddling issues which an LLM probably wouldn't be able to parse.
Considering the general attitude towards genAI on the network, tainted by events here, I'd think the reception to it actually happening would be chaos, unhappiness, and calls for people's heads.
The 'benefits' are not that great, and the potential for core users being deeply unhappy over this is why, as I'd said earlier - I'd rather the resources go towards development of the public platform and ancillaries, and ensuring comfortable staffing levels with minimal risk of layoffs, than spent on getting folks chatgpt plus access.
