I don't think this is a programming language fail as much as it is seeing everything as nail because you chose to use only hammers. In the world of programming and technology I wished more people would look at people who invest and see that diversifying is what you need to do sometimes. Pick the immutable database but have a solid regular one along side of it in case you need to jump ship (more cost but it covers the case that the immutable database doesn't work out). This is the difference between investment and gambling. I would say to some degree they betted on immutable being the thing that would give them success instead of investing in immutable technologies that could be useful.
