This is a hard and politically loaded question :)
The new world (.NET) and the old world (Python, Perl, etc) are really
quite distinct. To see all the benefits of .NET, you assume a world
based on .NET. So while .NET has some obvious and significant benefits,
it does require a leap of faith to fully exploit them.
I believe it will be a few years before .NET really starts taking off.
It will be lead mainly by corporates - people commited to being a
"Microsoft Shop" for their own strategic reasons. In my opinion, large
IT shops filled with mediocre programmers have very good reasons for
making such decisions, so I imply nothing negative about such places or
decisions.
I honestly do not know where Python and Perl really will fit in this new
world. .NET imposes certain requirements on programs, so that the
benefits of .NET can be realized. However, these requirements can often
work against languages such as Python. The dynamic and introspective
nature of Python is unlikely to be able to be exploited, unless .NET
itself grows these same capabilities - and when .NET grows them, we can
expect C# to also grow them.
For example, in the ideal world, you could implement a Python class with
__getattr__() functionality, and use that class from Visual Basic or
from C#. This is only likely to be possible if .NET itself grows
support for expressing this level of dynamic attribute access, and if
.NET itself has it, we could expect the popular MS languages to also
grow such features - ie, the equivilent of __getattr__ implementation in
C# or VB. Once everything gets to the point where Python can express
these things in .NET, why would you still use Python? As much as the
*syntax* of Python is very nice, it is not only the syntax that makes us
love the language - it is the language as a whole.
So if .NET has all the features necessary to allow Python to be fully
utilized by other .NET languages, many shops will simply choose to use
these other languages instead of Python - braces aren't *that* bad :)
If .NET never has this capability, it will mean that Python itself can
only take advantage of Python's features - so why use the .NET
implementation of Python at all?
But heck - I thought OS/2 was a sure fire winner :)
