It makes me want to cry, knowing we handled that with a single server and a relational database 10 years ago.
Lets also not forget that everyone today forgets that the majority of data actually has some sort of structure. There is no point in pretending that every piece of data is a BLOB or a JSON document.
I have given up on our industry ever becoming sane, I now fully expect each hype cycle to be pushed to the absolute maximum. Only to be replaced by the next buzzword cycle when the current starts failing to deliver on promises.
