What do you mean? Of course you can still learn them "just for fun" if you want. There are plenty of columnar data warehouses (memsql, greenplum, vertica, clickhouse, etc) and data processing frameworks (spark, flink, etc) that you can look at, implement and run yourself.

It's all using the same principles underneath.

What I'm saying is that you can surely scratch the basics from personal use, but it's completely different from real usage and such can only be trained on job. Now that those jobs are fewer as everyone goes on cloud.
