> why he regretted introducing Neo4J

Even for use cases Graph dbs knock out of the park Neo4j (historically, I haven't used it in like 10 years) didn't work very reliably compared to modern competitors.

But as always it's about picking the right tool for the job - I tried to build a "social network" in mysql and neo4j, and (reliability aside) neo4j worked way better.
