What is tailscale going to do with GPUs? It's about as far removed from NL interaction as you can get, I really don't see any sane AI fit. Maybe they are using them for AI driven dev work? Probably need to think more laterally.
The. fine. article. seems. to. say. lots. of. companies. are. using. Tailscale. to. connect. to. servers. with. GPUs. -- nothing. in. that. implies. that. Tailscale. would. own. the. GPUs.
Besides my joke, you are bang on, nothing implies needing to buy GPUs and based on my knowledge of their product/the space, absolutely no reason to.
