On: We built the fastest CI and it failed

It is a solved problem - you need to use a build system with sandboxing like Bazel, and also vendor all your tools.

Almost nobody does that because very few people realise it is the solution and even fewer realise they're going to need that before they set up their build system.

Switching to a build system like Bazel can be a significant cost, though.

There's no easy solution to making your builds go faster, if they aren't already. There's hardwork and artifact management (dependency hell).

Unless you are asserting Bazel is a direct competitor to Earthly, I don't think the assertion is useful at all.
