Yes, as nowadays we have the ability to simulate or experiment theories at a great speed. A century ago it was a lot harder so scepticism made sense as you couldn't easily prove your theory. You feel we should be able to take more risks now, but if anything we take as many or fewer, therefore I fear mavericks have become even less popular.

It is not that simple. People spend days, months, and years going down the wrong path. They aren't so willing to give that up when something that can replace it will throw all that work down the drain.
