What is 1+1? Would an AI be broken if it gave an answer other than 2?
If you expect "2" you don't really understand how LLMs work. For at least two reasons.

When multiple people add the same/similar event during EventStorming, don't immediately merge them.
The duplicates aren't noise. They're telling you something.
I'm running a public virtual EventStorming workshop April 14-17. Details: virtualgenius.com/workshops/

This closely matches my own recent experience with Claude Code. Important work that I deferred for far too long because of the almost-but-not-quite repetition over many cases (40 schemas in my case) that would defy traditional automation with home-made tooling. Claude did 98%.
Claude Code agents handled the tedious bits while I focused on structure. Not magic, but saved me days of manual work.
