I use mine on a sofa (for gaming, even!), but I get around the issue a bit by having a pad under the laptop. It’s literally just a hard plastic board with a beanbag attached underneath, I think I got it from IKEA. It isolates the laptop a bit from dust and improves airflow + lets it heat up without burning my knees + the one I have is just large enough that I can also use my wireless mouse on it when I push my laptop to the left.

I dunno about that, recent knitting drama took a while to clear up, and I’m not sure if AI sceptics are as determined a crowd as pissed off knitters.

(Tl;dr on the drama: there was video on SciShow about knitting that many (myself included) felt was not well researched, misrepresented the craft, and had a misogynistic vibe. It took a lot of pressure from the knitting community to get, in order, a bad “apology”, a better apology, and the video taken down.)
