Ehhhhhhhh. It hasn't really made a super convincing argument not to use SQL. A lot of what is described isn't intinsicly a SQL problem, but instead an ETL problem. Eg, the use of complex types can be done by loading a csv into a TEXT table and then test typecasting on a sample set, followed by the full set.

And geo indexes are no joke. Using them has made 8hr long SQL queries take seconds.
