My reaction was just the opposite. There are so many aspects of physics or other physical sciences that we take as basic knowledge and learn in grade school, but which were discovered years ago by some of the greatest thinkers of the past. It’s deceptively easy to wonder what it would have been like to live back then when the science was young and discoveries seemed more readily available. When you didn’t need to build a massive supercollider to validate theories. Of course much of this thinking is probably a fallacy... hundreds of years from now people will think similar thoughts about where we are.
And yet medicine quite clearly seems at this earlier stage. Think about how far we’ve come in just the last century... we’ve only known about antibiotics for 100 years and the structure of DNA for half that long. That’s not a reason to be dismissive, medicine right now is in its early days and the people doing the research are pioneers. Medicine today has so many opportunities for smart people to contribute.
