That is a pretty accurate description IMO, which is a view I've been advocating
for some time now. The fundamental flaw of the entire "new paradigm" discussion
is the style argument. A lot of Thorsten's speculative approach is based the
subjective and unscientific term "style", which obviously vary accordingly and
therefore completely nonsensical for any practical use.

The other problem is the development of GT. According to the author, as far as
I've understood, most of the framework is adapted from Tiger 13.0. Tiger 13.0 is
basically a knowledge propelled bean counter like a lot of the commercial
alternatives AFAIK, eg. Shredder, Hiarcs, Gandalf and others. This suggests that
at least the initial stages (GT still needs finetuning and modifications
according to the author) of transistion between the old and the new is trivial,
ie. anyone can do it with a little (or most likely a lot of) effort.

The mindbarrier assumption is nonsense as well. If there's ample documentation
that the approach works longterm then there will be a change, because the
essential motivation IMO for the creators of chess programs, is winning. The
introduction of the mindset argument is purely for egoistic reasons, because it
makes them sound like intellectual giants compared to the rest, which obviously
isn't the case.

There's nothing revolutionary about the program. At least not yet. In the next
months and maybe years we'll see a process of adaptation. Resembling the process
we know from the theory of evolution.

The adaptation will be as follows IMO: If the GT program proves to be
consistantly stronger than the existing programs then two things will happen.
The competition will focus on identifying and exploiting weaknesses of GT, which
can be of a positional or tactical kind. Maybe the speculative evaluation can be
exploited in some way(?). The other topic would be to contain and analyse its
strengths, eg. making king safety development a priority. This process, if
succesful, will undoubtedly be countered by CT, using the data and experience
he's been gaining in the mean time, watching the competition trying to solve the
GT "style".

A revolution, or a shift of paradigm, will have occurred if the process of
continued adaptation breaks the framework of the old system in a way that makes
progress impossible. Similar to ordinary evolution theory in the sense that the
prey fails to develop countermeasures against the hunter and becomes extinct.
This can also happen to the hunter of course.

So far there's nothing to suggest that the old framework can't adapt to the
threat. The only danger might be the lack of willingness to do so before it
becomes blatantly apparent.
