[ExI] Discontent with the path physics is taking

[scerir]

Dennis May (fwd by Dan):
I do have a horse in the race and it is certainly true that I view string theory as 
interesting
mathematics with little value in physics - certainly not enough value to justify it having
taken over virtually all of theoretical physics everywhere in the world. The 
popularizations
that are still published are virtually all in lock step with perhaps one partially 
interesting book
every 5 years or so about all you can hope for.


# Ed Witten in these lecture pointed out many good (but also bad) reasons
to follow the string theory approach.

But I can agree. All that sometimes seems boring and useless.

Not by chance new principles sometimes appear in the literature,
like this "principle of mediocrity" :-)

But the paper by Vilenkin seems good food for thought.
