|content=Said differently I’ve been bullish on positive externalities of mathematical physics. But a lot of great math that got done isn’t string theory. It’s claimed to be stringy but it is really mostly mathematical physics or geometric field theory that is claimed by string theorists. | |content=Said differently I’ve been bullish on positive externalities of mathematical physics.

|content=Things got hard. They didn’t get hopeless. | |||
Yes we spent almost 40 years lying about string theory. But we could stop today. We could have the leaders in the field admit they made a *colossal* bad bet & ask “What did we dispose of while we were wildly over-hyping string theory?” | |||

|content=Its increasingly apparent to me that the next physics breakthrough is gonna be from #ai . Its humanly not possible anymore for theoretical physicists ..i was feeling it even around 2010 | |||

|content=They can't stop, Eric. They're making a living from writing papers about things no one will ever see. It's a systemic problem that requires a systemic response. And the first step would be to admit they have a problem (which they don't). | |||

|content=Seems likely a lot of the math they developed will wind up handy, but it's a long time to wait for dessert. | |||

|content=Most of what physicists call math is totally uninteresting even for mathematicians. It's just advanced calculus. Look here is my qft and when I crunch it cross-sections fall out. | |||

|content=We may disagree intellectually more than I thought. This is Jackiw’s point: the era of physics thinking of mathematics as advanced calculus (analysis) wasn’t fruitful. | |||
That changed around 1975 when the quantum began to discover geometry. | |||
I’m honestly confused. What do you mean? | |||

|content=We are talking past each other. I am referring to particle physicists/astrophysicists/cosmologists who crunch out shallow and useless papers in the thousands. There's no interesting math in those. You're talking about something else entirely. | |||
