I see what you mean now on old is gold and yes I agree. Corporations love old proven tech for all the obvious reasons. Not officially deprecated but that's just semantics. The underlying point is that the Python leaders are trying to turn a superhighway into a dead end, and force a long and winding detour for most people onto another highway which is only marginally better. Being forced to take that detour simply encourages the exploration of other alternatives as well. By the way if they really had balls, they would've killed Python 2.7 in 18 months. Not 5 years. Force the choice. Clearly they themselves are not confident enough in 3.
