For now. One more ternary model type breakthrough, or MoE, engram thing (I don't fully understand those for the record, I just know they speed things up and use less VRAM) could see a few GB sized weights with quite the capabilities. On a gaming PC, savvy teens can already use them to cook up quite an interesting array of likely illegal items and substances. If it goes much further and runs on phones, you can assume word will get around that unlimited private AI is available and kids will run into all sorts of issues. Or mentally unwell people. I'm thinking a year or two down the line only.
