What are some misconceptions or areas of confusion people have around the Taproot upgrade?

For example, it’s actually three things:

1. Schnorr,

2. Taproot,

3. Tapscript

I was today years old when learned the Taproot part of the upgrade is not just the idea of using Merkle trees (to only revealing spending paths used).

It’s a technique (using a public key and a Merkle tree) to make a coin spendable by either public key OR script. You can’t do any of this without Schnorr, at least not in a way that is remotely reasonable.

I think it’s very confusing that the entire upgrade, the entire package of things, is named after a single feature, even if it is the one that ties everything together into a nice, impressive use case!

There are plenty of interesting things about the Schnorr and Tapscript components, but they are often referred to as general “taproot” in discussion.
