larger companies responded by offshoring R&D to countries with more favorable tax regimes, leading to U.S. job losses. For example, Google reportedly shifted some work to Germany, and Microsoft moved a bunch of research work to China - both because pay rates were better and because the local subsidiary company in that jurisdiction operated under the national laws for that nation, which … were not the US tax laws. They were much more like the previous US tax laws, because the rest of the world had realized “hey, we also want to encourage people to invest in R&D and grow the next trillion dollar company here!” And this new tax ruling doesn’t precisely say “we don’t want to do that” but it does say “we don’t want you to be quick about it” - which everyone who believes in the Amazing Growth Story thinks is anathema to their strategy.

Anyway, the impact of this tax strategy turned out to be: layoffs of U.S.-based engineers while companies restructured operations abroad.

“Psychology like mine prepares for an end or even for the end. The question is only, what are we going to kill: ourselves or our still infantile psychology and its appalling unconsciousness.”

The fix: From O(N²) to efficient mapping

To resolve this performance issue, we contributed an upstream fix to Git that replaces the nested loops with a map data structure. Each reference is added to the map, which automatically ensures only a single copy of each reference is retained for processing.

This change dramatically enhances the performance of git bundle create and enables much better scalability in repositories with large reference counts. Benchmark testing on a repository with 10,000 references demonstrates a 6x performance improvement.

For some features, vibe coding also simply does not feel responsible. For example, when dealing with money. While the UI of the eCash wallet was largely vibe coded in Chorus, Calle coded most of the actual Cashu implementation by hand to be sure that he knew and could trust that the user's money would be safe with us. However, Jack did also vibe code a working Cashu implementation with Goose — proving that it’s not impossible, just dangerous.
