Thank you Ariel, though the article was written as a speech and it is quite general. First of all I had only one month plus few days to write it, and the subject (which seemed to be quite obvious for me) appeared to be very complicated. So I decided to not to involve in detailed disputes as with karabela case, where many different ideas are still under discussion, but focus on main problem.
The book would be very interesting, I agree. But there is still a lot of work to do with the problem so maybe in the future. On the other hand I could only rely on already published researches and add only few of my really original thoughts - there wasn't enough time to do my own investigations
Regards!
