No.
An idiot giving you 100% will never learn your product.
A genius giving you 1% will eventually develop a highly optimized way to use your product.
If we assume all users are the former, we never design for the latter. That pretty much sums up the last 20 years of de facto UX.
And if you disagree, I'd recommend you go find a call center still using mainframe apps, and watch a random sample of 100 users.
