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.
