It's not enough for some companies that need to ensure it won't happen.

I know for a fact a major corporation I do work for is vehemently against any use of generative A.I. by its employees (just had that drilled into my head multiple times by their mandatory annual cybersecurity training), although I believe they are working towards getting some fully internal solution working at some point.

Kind of funny that Google includes generative A.I. answers by default now, so I still see those answers just by doing a Google search.
