Telicity matters, Janski.
(A)telicity has nothing to do with it.
(1) I am going to be traveling (a lot). (Atelic)
(2) I am going to travel (a lot). (Atelic)
Freed from the scope of "be going to", the complements in isolation:
in (1): progressive infinitive "be + traveling" : atelic
in (2): simple infinitive "travel": atelic
You talk nonsense. (atelic)
You are talking nonsense. (atelic)
So what's the difference?
