I try to think of it like if there was a programming content creator saying Elxir is powerful and ready enough to use everywhere. Though it is true enough that it can be used anywhere, but anyone here could probably point out a bunch of situations you really should never ever use something like it. But imagine someone without that experience not knowing and taking their word for it and put it into prod blindly, it be a huge waste of time and money. Time and money is one thing but in health, knowing media and reading literacy is dropping, its just something if I where in his position I would see it as irresponsible to even mention some of the stuff he does.
