For me, December's issue of Scientific American was the best in perhaps 35 years - thanks to the Lisi-Weatherall article. Now, how about a 70-page Special Issue to expand on the dozens of concepts that tantalize non-specialists like me?
The appeal of E8 is so deep that it will surely count as the biggest disappointment of the 3rd Millennium if it fails to model reality. I wonder if the same objections still hold as you reported in March/December 2008: "One way of stating the problem is that if the new theory really describes bosons and fermions, then the structure it places them in cannot possibly be a Lie group at all."
Leading-edge physics is littered with claims and counter-claims that turn out to rely on unwarranted assumptions or exhibit unexpected loopholes, so this particular argument probably still has a long way to run. Congratulations to Mr Lisi for having had a vision and the courage to promote it in the teeth of spectacular venom (and jealousy?).
His relief is palpable:
