If there were 11,000 open and confirmed bugs then yeah, that would mean the software is bad.
But also, if they all use 500 agents daily and latest models can "one shot" everything, one would think 5k issues are fixed in no time...
Havent used CC in some time, worked fine last time I tried.
One example of what is particularly bad with it: tool calls and progress. Codex UI does it so much better. The way in which CC waits for a task to complete etc is really poorly done compared to Codex.
Another thing that's missing: no way to continue a side chat in Claude Code - this is easy in Codex with /side and it is super usefu.
I don't think Claude Code is perfect software, but I don't think fact that Codex has a slightly nicer implementation of certain patterns makes Claude Code bad software.
