Nope. Nothing but industry-wide inertia is so massive by now that it just doesn't make sense to switch. Nosqls tried hard and went nowhere.

What i find funny is that most dbs translate sql into an internal representation that is remarkably similar to a proper relational algebra and optimise on that. I'd really just prefer the alebraic language as described in the original ages old paper.

There were also a few dbs trying to push sql-but-better languages... haven't heard about them for a while.
