Yeah the post seems to confound two mostly unrelated issues. I agree with not reinventing the wheel for relational databases, SQL is fine. But for other domains, the query languages arose out of need, not because someone felt like it. SQL is hot garbage for for non-trivial logic. I can't even imagine what splunk would look like if you had to query it with SQL. If anything, SPL (or rather the piped operators approach) would make a lot more sense as the groundwork for a universal query language that works across many domains.
