Python has been acceptable and widely used for more than a decade. It's one of the most popular languages right now. Claiming that CΡUs are not fast enough for Python is not only disingenuous, it is dead wrong.
Normal people refer to market penetration charts for CPUs and see what is actually in use today, check trends for the near future and design software to run on what people actually use. If you did that (and it's quite obvious you haven't) you'd see that Python, even Ruby, are quite acceptable for modern software - if they weren't, you can bet they wouldn't be quite as popular as they are.
Those are substantial portions to me. And the real outlook is likely worse than that, for reasons such as the business group.
