Tom Green on Flash to HTML5:

'''Rather than become an Adobe apologist – which they sort of expected – I told them . “Welcome to your new careers. If you can’t deal with this sort of change on a regular basis … there’s the door. Go get a refund and go drive a beer truck.” It was a great opportunity for me to review all that had been going on, what happened,and what it means for them.

The thrust was technology changes and you either embrace change or get out of the way. Change is a fact of life in our business and, as a teacher, it is a fact of life for me.'''

I shouldn't have to mention it, but I will. This obviously applies to so much more than Flash.
