Yes indeed Bruno. As far as I tell tell, all of physics is ultimately
geometry. But as we've pointed out on this list many times, a theory
of physics is *not* a theory of everything, since it makes the
(probably false) assumption that everything is reducible to physical
substances and properties. Thus we both are in agreement on this, but
for different reasons (you because, you think math is the ultimate
basis of everything aka COMP, me, because of my property dualism, aka
the need for a triple-aspect explanation of physical/teleological/
mathematical properties as the basis for everything).
We keep telling mainstream scients, but mainstream scients are not
listening to us. *sigh*.

There's too many people mucking around with physics - I do wish more
people were working on computer science. Physics is the most advanced
of our sciences, but computer science lags behind. It just seems to
be an unfortunate historical accident that physical theories developed
first and then lots of social status got attached to theoretical
physics (stemming from the glorification of Newton in Europe).
As a result, physics has advanced well ahead of comp-sci, and there's
lots of money and status attached to physics breakthroughs. But comp-
sci is actually far more important to us in practical sense -
artificial general intelligence would be way way more valuable than
any fundamental physics breakthrough. We would have had real AGI long
ago if there was the same money and glory for comp-sci as there is for
