V.1: Ringo Starr is shit at playing drums.

V.2: He's actually a good drummer and lots of professional drummers will tell you how underappreciated he is blah blah blah blah blah blah blah.

I'd imagine V.3 will see us return to the acknowledgement that he's utterly useless.

Using the above as an example, provide other instances where received wisdom has changed over time, and detail those changes. Also, provide an indication of future changes you believe may occur.
