It's strange. The biggest change isn't with the evidence, but with the narrative. For decades it was just pure crankery, but now we have 60 Minutes with a big episode with US Navy pilots, Obama talking about it, the mass media, late night shows, etc, all taking it seriously. This all would have been considered crazy just a year ago.
It would appear we are being prepped to get comfortable with a new narrative. Sam Harris, who I'd consider trustworthy and hard to fool, was given a heads up about what's to come. If he's right about his source being reliable, then we may have to have to contend with this:
"I got contacted by somebody who gave me a heads up with respect to all of this happening and he more or less told me listen, when this other shoe drops you’re going to be in the position of having to acknowledge that all the experts are on the same page, and there’s just this blanket declaration that we’re in the presence of alien technology, and we don’t know what to make of it. So prepare your brain for that and figure out what you’re going to do."
