This should be apparent to anyone who observes fundamental physics. The 20th century saw massive increases in knowledge with relativity and then quantum mechanics (ie QM/QFT/QCD). There have been accomplishments in the 21st century but a lot of then (eg the Higgs boson) were confirming things theorized 50+ years ago. Despites decades of trying we're still to find a crack in the Standard Model. Yes we've eliminated a lot of options and that's important in the process of elimination but we don't really seem to be any closer to resolving the fundamental contradictions of QM and GR. There's a fun list of unsolved problems in physics [1]. My favourite is the so-called vacuum catastrophe [2] where the predicted (from QFT) and actual vacuum energy diverge by roughly 120 orders of magnitude. At the other end of the spectrum is the magnetic moment prediction vs actual [3] that differ by less than 10 parts per billion. I'm actually losing faith we'll see meaningful progres sin a lot of these areas in my lifetime and I never used to think that.
