Very very true. Nowadays many promonent physicists stake their careers on stuff like String Theory or Multiverse Theory, when neither have any direct evidence to back these up, other than "the math makes sense". That's why it's very refreshing when you hear scientists in places like CERN say "we hope we're wrong because that means we get to make new physics". And also why this year's Nobel Prize for Physics is a big deal: they managed to prove Einstein wrong as well.
