I think his basic criticism of toolkits in general is quite valid.
There is no doubt that "simplifying" abstractions can make it very hard
to actually do anything the abstraction isn't specifically designed to
handle. Which is particularly frustrating when you know exactly what
you want to do on a low level.
But (as has been pointed out before) his suggestion to write your own
toolkit is horribly misguided (unless you have extremely limited
requirements, such as "only has to work for me"). And his dismissal of
a random set of more or less unrelated technologies seems borderline
nonsensical. (He would rather use C than UML to explain abstract
concepts to other people? He would rather write his user documentation
doing there anyway?)
(And yes, I think declarative UI design is a good idea. But I don't
know how to design such a system to provide both the simplicity and the
flexibility you would want.)
