You’re lamenting that inventing boats has destroyed the beauty of swimming.

Responding to your expanded argument:
You could never swim to a new continent, which boats enabled. This is the same — people can choose to keep doing the same limited math themselves, in a slower way, but will never reach the places people can aided by tools. That’s simply how the world is. But we shouldn’t restrict the distance people can travel to adhere to the aesthetics of swimming.
You’re arguing precisely that: we must limit our intellectual journey because you don’t approve of the aesthetics of the tool to travel further.
