Tongue-in-cheek aside, the author's point is that regardless of its current status, MongoDB has been pushed on a lot of people hungry for performance/simplicity; in that singular pursuit they may be setting themselves up for disaster later on. Most developers have a (perhaps unspoken) assumption that a successful write to a database means that data Will Not Disappear. If Mongo violates this assumption, then either developers' attitudes have to change or they should look at other software to avoid being bitten.

Take something like sockets: by using TCP, I am telling my development environment that I would like an unbroken, sequential stream of traffic to another endpoint. Just as importantly, I would like to be notified if this ever is not the case. If I discovered errors in my TCP stack, I want those fixed pronto because any kind of workaround would be reimplementing the very task TCP is meant to cover -- I might as well write my own sequencing and retransmission logic on top of UDP!

Then I think it is way easier to write a post "Do not use technology, go back to the cave". Any technology has chances to fail, can be SQL, Cloud, yadda yadda. And if you want to work on the 'edge' (innovating to disrupt your competitors), that's a risk you should accept. Blaming the tools you use to achieve that point is childish.
