There are many leetcode champs who are completely helpless in front of a computer.

The premise of emphasizing leetcode is to get developers who can solve problems fast.

But if the only thing someone knows is competitive programming, and not operating systems, distributed systems, network protocols, serialization formats, libraries and frameworks and pretty much everything that's required to implement actual software, that person won't be able to solve problems fast. In fact, that person may reinvent the square wheel and waste resources.
