This headline is a great "grabber" for older bankers and financiers. It implies that the whole "bitcoin thing" is finally blowing over, without going out and saying it. Music to their ears.
It seems far more likely that you do not, actually. There are thousands of extremely intelligent people working in finance with a lot of domain knowledge -- in the case that something as widely publicized and easily studied as bitcoin is not being taken seriously in finance, it's far more likely that there are serious issues you don't understand.
