it's unfortunate the amount of expertise / tinkering required to get "incrementalism" in docker builds in github actions. we're hoping to solve this with some of the stuff we have in the pipeline in the near future.

The fact that GitHub don't provide a better solution here has to be actually costing them money with the network usage and extra agent time consumed. Right?

[aayushshah15]

GitHub has perverse incentives to not fix this problem because they charge customers based on usage (by the minute), so they make more money by providing slower builds to end-users.

They've also just completely refocused to AI in the last two years thanks to the microsoft/ChatGPT situation.
