Today's AI and today's internet are just not yet suitable for each other. Doesn't even look like they are moving in the right direction.
I don't foresee trusting MS Office itself to be exposed to the internet ever again any more.
Especially with Windows 11.
I wish it wasn't so, but I for one certainly would never allow Copilot to exist on an office machine.
Even more of an emphatic no if it was not just an office machine but a business machine.
