Regardless of what you think about AI, its impacts, and the ethical considerations, it's been clear for a long time that the people running AI companies--Altman et al.--are not acting either ethically or sincerely.
This is a publicity stunt at best. Asking unethical people how to make things more ethical isn't a workable idea.

One could argue the same is true of many religious leaders so I'm not sure what to do with the news of this meeting other than shrug.
(this is not meant as any kind of defense of the AI company executives, who should continually be called out for their unethical behavior)
On the other hand, perhaps this is just responsibility laundering on behalf of the tech orgs.
