Isn't it wasteful to have everyone go off and remake the same software with slightly different bugs in it instead of one that fixes almost all of the bugs

Terribly wasteful, yes, though perhaps if the idea caught on the major labs could stand some chance of long-term profitability.

Seriously, I wonder how many tokens are generated (wasted) every day on someone recreating another agent memory, context management, code graph, etc.

I can’t wait until Qwen 4.5 27B or Gemma 5.
