Ultimately, the problem is people aren't actually benchmarking any of these ideas or if they are its via an extremely misleading methodology. For example, headroom violates cache frequently, nullifying any potential savings it could have; but does their benchmarks show that? Nope. [1]
As an aside, I wonder how many days are we away from Codex or Claude taking all the "read" tool calls and re-assembling a full map of your codebase and then offering it as a feature.
I have more faith in companies with a more targeted approach. Eg gzip does fine, but video codecs beat compressing raw video by a ton.

That sounds like SourceGraph but twice as expensive, although it does have “AI” so probably lol
