I don't understand the sentiment. OTEL is better than anything I've ever used before. Do I like every part? No. My personal no-no is the automatic instrumentation which I always bypass and just DI it myself, I don't like the "global" by default approach in Golang and I had to fight team mates who were all for using it. That said, no other observability library that I've ever used was so good overall.

The perf is meh, but tbh if you look at the kind of code we, regular developers write for work, it's probably still vastly better.
