Grok makes it trivial to create fake CSAM or other explicit images. Before, if someone spent a week on photoshop to do the same, It won't be Adobe that gets the blame.
Same for 3D printers. Before, anyone could make a gun provided they have the right tools (which is very expensive), now it's being argued that 3D printers are making this more accessible. Although I would argue it's always been easy to make a gun, all you need is a piece of pipe. So I don't entirely buy the moral panic against 3D printers.
Where that threshold lies I don't know. But I think that's the crux if it. Technology is making previously difficult things easier, to the benefit of all humanity. It's just unfortunate that some less-nice things have also been included.
