One of the striking things about LLM-s is verbosity. A junior guy had to do some task and create docs how (a rather simple) change needs to be done. He produced, using Copilot (all those hyphens, additional lines between paragraphs, etc.) , a long dissertation that included some rather poor analogies and that could have been summarized in 5 sentences. Yet I had to go through that writing.

Same with the code. Generate Apache Kafka listener using Spring Kafka. Here you go, my human boss, the code is ready. The code is ready, but, somehow some outdated tutorial or Stackoverflow answer must have kicked in, hence it produced some totally unnecessary factory of factories that Java loves so much, but could be replaced with a few lines in the properties file.

But, when notified, Copilot kindly agreed that that factory is not really need and I am right.
