I'm inclined to agree with you. It's not my field but I suspect VC pressure has something to do with it: they need their 10x returns, or their unicorns, to make up for all the losses elsewhere and "get big fast" is the most reliable mechanism for doing that. Not suggesting I'm a fan of it, btw.

It's a market issue. Databases are a very competitive business with lots of options and competitors. It is also extremely hard to sell.
