I don't know the answer either. It would depend on empirical measurements
of how productive I am for my typical tasks in Python vs Magicklang, as
well as on subjective measurements of how much I enjoy using either, etc,
etc, AND market demand (effective demand, as in $$$-offered;-) for my
services in either capacity. E.g. if Magicklang had perfect compliance
with .NET, Python yet hadn't, and oodles of customers were beating at
my door, bags of gold coins in their hands, desperately pleading for
.NET applications and consultancy, then my switching to Magicklang for
this purpose would be far from impossible -- I doubt the type inference
could be as destructive of my productivity and enjoyment, compared to the
dynamic typing alternative, as to make me refuse the $$$ in question, if,
as you say, Magicklang was so beautifully designed and Python-inspired...
