There is an extremely narrow band of things that the AI shouldn't be answering, and that is generally immediately-actionable advice that allows someone to build something of harm to others. But even then, in an age where Tor, bittrent, i2p, abliterated local models, etc are freely available, let alone numerous books and online resources, is there even a point? Is it worth fully compromising the principles of free agency to an increasingly oppressed populace?
But instead of that we are handing the keys to regressive and repressive governments to order the suppression of any knowledge they deem inconvenient. I really doubt anyone is going to take a principled stance when the company's party minders threaten local staff with a rubber hose or incarceration.
I'm sure China et al are already doing this.
For the past 30-40 years humanity has received an incredible gift in these sand-powered thinking brainboxes. A gift that allows the common man to empower himself with a force multiplier towards his own success, and now access to superintelligence the likes of which few have ever seen. These can be tools to destroy the oppression that governs our lives from foolhardy, greedy, bootlicking control freaks. And here we are squandering it.
