Snakes only produce a small amount of venom and it takes days to replenish reserves. They have fine muscle control over how much venom they release and scientists have measured them releasing amounts of venom relative to the size of their target.
Not sure how aware they are of doing it but I wouldn't be surprised with all of a viper's sensory organs that they knew venom would go to waste on a prosthetic
AMD is doing really great things with APUs like the Steam Deck. I just got a travel mini PC with a Ryzen 7 7840U. It can play most games at 1080p high quality with 30fps and fits in the palm of my hand.
It might be a while before you can play VR on an APU but they're already comparable to GPUs from 5 years ago
