Big databases are not new. If that was all that was needed, people would have been doing just that for the past 40 years. Turns out it doesn't always work, and sometimes (often?) it's terrible. Even if theoretically it was all you ever needed, the other constant problem is the implementation. Most developers, today anyway, are morons. They don't understand how databases work or how to use them, so they use them poorly. In order to get away from that fact, they invented new databases (like NoSQL) so they could use their brains less and just write more glue code. Turned out that was horrible as well. Pretty soon the tides will turn yet again and "just having a big database" will again be seen as not in vogue and another paradigm of "simplicity" will come around (instead of "one big database" being simple it'll be "many small databases" like we had with microservices). Those who don't understand history are doomed to repeat it.
