Dear Jeff,
I understand your pessimism. I dropped out of grad school (after I had qualified for a Doctorate in Solid State Physics) once because I didn't like being a faceless, proletariat gear. I once swore off physics and higher education. Years later, I chose to go back to grad school. My perspective was completely different - I didn't want to "simply survive" grad school - I wanted to be one of the best.
I enjoy living, thinking, and spending time with my wife and daughter, and I'm not yet ready to be burned at the stake. But at least we remember Bruno's name. Is it better to be a faceless, proletariat gear that no one remembers, or to be the guy that everyone remembers for being burnt at the stake?
Modern physics is at a standstill because experiment has not advanced as quickly as potential theories in recent decades. Not only are the experiments technologically difficult, but we have fewer monetary resorces in this difficult economy. To my knowledge, there is insufficient experimental confirmation of strings, CDT, and holographic gravity. But we know that reality has a dual wave and particle nature, and that holograms require BOTH concepts to work.
Have Fun!
