I'm increasingly coming to the view that there is a big split among "software developers" and AI is exacerbating it. There's an (increasingly small) group of software developers who don't like "magic" and want to understand where their code is running and what it's doing. These developers gravitate toward open source solutions like Kubernetes, and often just want to rent a VPS or at most a managed K8s solution. The other group (increasingly large) just wants to `git push` and be done with it, and they're willing to spend a lot of (usually their employer's) money to have that experience. They don't want to have to understand DNS, linux, or anything else beyond whatever framework they are using.

A company like fly.io absolutely appeals to the latter. GPU instances at this point are very much appealing to the former. I think you have to treat these two markets very differently from a marketing and product perspective. Even though they both write code, they are otherwise radically different. You can sell the latter group a lot of abstractions and automations without them needing to know any details, but the former group will care very much about the details.
