That was not my point in the first place, know you. I am not an expert nor regarding flash or HTML5 so I do not have a clear opinion of the matter. The time will tell the limits and possiblities of HTML5.
Clearly the fathomised 2 BILLION VIEWS OMG!!1! must be a great thing for flash. As far as I know Google and Adobe are in fairly good terms. What if they were not?
If Youtube switched to HTML5, most of the people using Youtube would not notice. Nor care. As long as it worked. Also, there lies the greatest momentum for bringing HTML5 to general public.
I really did not get your point either
