Most people don't understand how to benefit from existing databases anyway
Instead of developing NewShinyThings (TM) how about we consider this:
Most people - even seasoned software engineers - don't even understand how to get the most out of "old" platforms like MySQL.
20 years ago I was developing small websites which used MySQL as their database. After a year or so I thought "I know a lot about MySQL now". Wrong - I did not.
Even after using it for nearly 2 decades I'm still finding ways to improve the way I work with it. The limitations of the DBMS have never been above the limitations of my knowledge.
It seems that the older platforms focused on doing a relatively small number of things extremely well.
These new technologies have a very 2022 feel, i.e. marketing and bullshit over actually being decent capable technologies that are fit for purpose.
If you think the bottleneck is with existing DB platforms, it's not, it's your knowledge (or lack thereof) in how to use them to their best. Do some reading instead of wasting time on this kind of stuff.
