I love Python, but it isn't right to compare it with Squeak. Squeak can be ported to bare hardware, it can be re-written in itself, and its speed is comparable with native C complied code even with the bytecode compilation. The author of this story was mistaken when he commented that it could be "slooow". It is fully possible to write an OS in Squeak without undue slowness, especially compared to the current breed of bloated OSes written primarily in C and C++. Add to this the superior portability and true, clean OO thanks to Squeak's Smalltalk heritage, and you'll agree that Squeak is what Java wants to be when it grows up.
