Yeah. When I was introduced to Go a month or so ago, I pretty much lost interest in Python for server programming almost overnight. Go is almost as easy to write as Python, has static types, and is MUCH more performant.
As for the 32-bit issue, who cares? Is anyone in their right mind still using 32-bit servers? (Ok, I'm sure someone will provide an example of someone who is, but even then they should be looking at migration to 64 bit sometime in the next few years.)
If we back up from Python and consider our entire community, this is a good thing. We don't (or shouldn't) necessarily want *Python*. We want a good solid language that is a joy to use and performs well. Python has been great, but I think Go rightly deserves to be its successor, in many applications anyway.
