Agreed. The hype around Big Data is dead, but a decent portion of the tech that came into existence during this hype cycle is not dead. Things like Hadoop have their stay in Fortune 150 and 500 companies, there's plenty of Hadoop jobs still out there. It's certainly not sexy anymore though.

Hadoop may be losing its foothold though from what I've seen, these days people are getting by just running beefy Linux machines and doing everything in Python using Dask. Most people are not doing petabyte scale data analysis.

I think this is the point the article actually makes, but I went into it expecting to see how it's been hard to extract business value from all this data, and then expected it to explain how the demand these easy-to-scale DBs induced resulted in even less value, but it didn't really touch on that.
