Being erudite is impressive. Clarity is a gift.
We've built entire institutions around rewarding the erudition. Academic papers written to impress reviewers. Presentations loaded with terminology that signals you belong. Consultants who make simple problems sound complex because complexity is what justifies the invoice.
The hard direction is toward simple. Anyone can add complexity, you just stop editing. Getting something down to where a curious 12 year old says "oh, I get it" requires actually understanding it. You can't simplify what you don't fully own. Jargon is usually a sign you're not quite there yet.
Feynman treated his inability to explain something simply as his own failure. Most people flip it, blame the reader, protect the complexity because the complexity protects them.
Simple ideas are also easier to attack. Complex ones hide behind their own density. There's exposure in clarity. You're taking out all the places to duck.
The best teachers I've had made me feel smart for understanding, not relieved that I'd finally kept up.
That's it. That's the job.
