While UML/Nocode tools were (and remain) a mistake, I don't think NoSQL was one. I might dislike some solutions in general but stuff like Redis, DynamoDB, Cassandra, Parquet and many others have produced a renaissance in databases that we would not have seen if it was all in the hards of the relational database vendors.
MongoDB easy (in a way) replication put every single database vendor on watch and led even PostgreSQL to improve, i think we live in a different environment right now due to all the experiments the NoSQL folks made. It might not have all panned out but I think the whole thing was a huge positive for the market, people stated to experiment and try new stuff again instead of "oh it doesn't look like a relational model, it sucks".
