It is difficult to evaluate the positive/negative effect of such an advertisement.
But I think you heard what you wanted to hear. If you have no relation to astrophysics, then you are unlikely to be interested in scientific research by Howard, for example.
I think that's actually a really good point. If this were a forum about model trains, would we naturally assume that the average member of the public will take an interest in that every time a particular character talks about it? Because, having watched a lot of that show, I can guarantee they've talked about model train collecting on far more occasions than they've talked about Bitcoin. And I certainly don't feel any particular inclination to get involved with model train collecting just because they talk about it on the show.
It might be more realistic for people in this thread to take their excitement down a notch.
