I think the reasoning is like this: - People choose Python to get ease of programming, knowing that they give up performance. - With multi-core machines now the norm, they’re relatively giving up more performance to get the same amount of ease of programming. - so, basically, the price of ease of programming has gone up. - economics 101 is that rising prices will decrease demand, in this case demand for programming in Python. - that may be problematic for the long-term survival of Python, especially with new other languages aiming to provide python’s ease of use while supporting multi-processing. So, Python must get even easier to use and/or it must get faster.
