The article presents no evidence that Pascal is faster than C++ other than in a given amount of time the Pascal programmer will have more time to optimize than the C++ programmer - and no citation is provided for that statement either.
No mention is made of modern Pascal development environments and libraries needed to build modern applications. My experience is Pascal peaked in the 90s. What tools and libraries would I use today?
These are the interesting questions I would expect an entry such as this to touch on.
