Drawing parallels from economic history, the article suggests that early market leaders often don't maintain their dominance. Just as early car manufacturers and dot-com era companies faded, the first mover advantage in new technologies is not guaranteed.

For instance, Tesla, an early EV leader, faces increasing competition, and companies like Google and Uber weren't the first in their respective fields. The article posits that Lean, despite its current standing, might face similar challenges if a more user-friendly alternative emerges.

The economic incentive for improving Lean is questioned due to its free availability and the mathematically community's perceived economic irrelevance. However, as mathematics increasingly drives future innovations, major tech companies may invest in proof assistants, potentially leading to more advanced and competitive tools than the current version of Lean.
