The "shovels for gold miners" analogy is generally a good one. It applies to Nvidia, for example. It doesn't generally apply to developers though. Developer tooling is notoriously difficult to monetize. Developers themselves are a shovel.

Devs are hard to market and sell too I've heard. It's likely because they can build a lot of the stuff out there themselves when pressed. They have the most app exposure so are opinionated. It's why most devs take the open source spoils while everyone else avoids GitHub in general. Although AI has made it easy to setup locally, many still don't see the value of controlling their software or ai agents fully like devs.
