I would have to agree with you, choice of language does not give a 60x productivity gain. However, it's not crazy to think that a really top notch engineer, who is an expert in Python, and who is operating on a much healthier and efficient team would give you a 60x improvement. Heck, 60x might be too low. It's not a priori crazy to find a 60x productivity difference between two teams. What is the productivity improvement between one team who spends 1 year on a project and fails to deliver it, vs another team that delivers the project in 4 months? It's not 3x, because 3x better than nothing is still nothing. The second team is literally infinitely more productive.
