I saw the best minds of my generation destroyed by madness, starving hysterical naked,
dragging themselves through the negro streets at dawn looking for an angry fix
According to Peter Woit in "Not Even Wrong" Ed Witten is the Tim Leary of physics destroying a whole generation of particle theorists on an insane quest that boggles the rational mind. On the other hand, hearing the Susskind-Linde Stanford Duet is very seductive music to the ears and it is understandable how so many poor little lambs have been led astray.
It's still too early to say for sure. Susskind's imagery of 6D Calabi-Yau spaces as "DNA molecules" whose moduli, fluxes. branes and orbifolds pinpoint where we are on the cosmic landscape of the megaverse is seductive as was Linde's impassioned soliloquy repeating Brandon Carter's argument that the many Anthropic coincidences only make sense if there is an actually populated landscape of causally disconnected pocket universes outside each other's de Sitter dark energy past and future horizons. Of course, a slight change in the rules of quantum theory to allow entanglement "signal nonlocality" violating the no-cloning theorem makes the pocket universes directly observable in principle though severely impacting Lenny Susskind's notions of information loss through horizons. So Lenny is stuck between a rock and a hard place.

Lenny called his talk "Rats leaving the sinking ship." "ship" = reductionism. However Lenny called "emergence" = "reductionism" in reverse POV. I am not sure if I agree with that. I am not sure if ODLRO "More is different" can be viewed that way. I say that with emergent ODLRO bottom -> up emergence (related to effective low energy field theories in flows of renormalization group?) is not simply the flip side of reductionism since it is non-perturbative).
Lenny wrote my basic equation that I use over and over again in Super Cosmos to make some model calculations e.g. charge clusters
F = ma = GMm/r^2 + mc^2/\zpfr
For a simple Lorentz-Poincare electron
ma = @e^2/r^2 + (hbar/2)^2/2mr^3 + mc^2/\zpfr = 0 equilibrium
Solves the finite classical electron problem with /\zpf < 0 dark matter core.
i.e. @e^2r* + (hbar/2)^2/2m + mc^2/\zpfr*^4 = 0 stable equilibrium
@e^2 + 4mc^2/\zpfr*^3 > 0
@ + 4(mc^2/e^2)/\zpfr*^3 > 0
@ is shell shape factor.
Extending to charge cluster is trivial.
Linde - "multiverse is a feast with all dishes served"
Gravity energy + matter energy = 0
Guv + /\zpfguv + kTuv = 0
Quantum fluctuations inflate when /\zpf stays constant from viscosity like in damped oscillator - slow roll.
Jiggle of the Higgs scalar ODLRO field at bottom of landscape well heats up the big bang creating on-mass-shell matter.
Coincidence problem means Weak Anthropic or else intelligent design.

Just got back from Hilton. Surprisingly Sean Carroll was there asked a question but I forget what it was. Lenny looks great - very Regal Shakespearean, but with the voice of Sid Caesar in The Show of Shows. He even had a slide of Woody Allen. Linde is also a good Russian comedian. Linde gave an impassioned impromptu answer at end to a question showing is real motivation for the landscape multiverse before in early 80's really identical to my own - more on that in another message. I have almost finished Peter Woit's book "Not Even Wrong." Peter writes well and is very convincing so it was propitious that I went to hear Lenny and Linde speak on how inflation and string theory reinforce each other in a way not totally disconnected from up-coming experiments like PLANCK NASA Probe. Lenny says that even a positive space curvature of 10^-3 would be trouble for multiverse-inflation. Lenny admits to the basic issues raised by Woit, but the situation is more complex. More on this to come. The situation is not as bad as Woit paints it, but not as good as Lenny wishes. When I spoke to Lenny personally he agreed that signal nonlocality using entanglement (a violation of orthodox QM - see papers by A. Valentini) would make the landscape directly observable, but it would spoil other parts of his theory connected with no-cloning. Lenny said he is not ready to move into that area of speculation - so I guess it's up to me (also Cramer's retrocausality experiment will be crucial). Someone mentioned Lee Smolin and Lenny said "who"? He pretended not to know of Smolin's work - a joke. ;-)
PS Krauss showed how dark energy proves Worst Possible World, i.e. life not sustainable. Some talk about string theory as religion.
