Has technology made us lose any capabilities so far?
Everywhere I look there is someone preserving 16th century cave painting techniques or hand tanning beavers and then writing guides that surpass whatever knowledge there was centuries ago.

You don't know what you don't know. Just because you know of some things being preserved doesn't mean all knowledge is being preserved.
For example, the US has lost its ability to do all sorts of manufacturing.
Businesses don't tend to document internal processes publicly. As those businesses die out and the people who worked for them retire, there is no one left to pass the skills along.
That's why the Army always keeps one tank factory open. So the knowledge and skills are not lost.
The knowledge isn't in practice but not lost. We still know how to weld steel and built turrets. I mean the full schematics of tanks are available online.
I'm not as worried about "business processes" dying. Who cares how Freddy does submits his TPS report.
Saying we know how to weld so we can build a tank is like saying we know C++ so we can build a new unreal engine.
If epic games went out of business, and no one worked on game engines for 30+ years, the knowledge would be lost. Even if the source code or “schematics” are available.
You need to know why things are the way they are, why decisions were made, what the limitations are, etc.
