Metadata vs Folders

The answer is both! Folders are connected to channels in Teams - and they really aren't evil! They do help organize content and if you want to work with content offline, you often don't want to sync an entire library - so having folders really helps. The challenges I find with folder are when you have multiple levels of nested folders. That's where metadata often provides a much better organizing framework. Metadata is far from dead - in fact, it's just as important as ever - but for many simple collaboration scenarios, folders are a good way to organize information. So, it's not either/or - it's both, as long as you try to limit to 1-2 levels of folders. There may be some use cases for more levels, but it makes information discovery much more complicated so it's not a great approach from an information architecture perspective. That's where metadata can really help, especially when content really "belongs" in two contexts. One of my favorite announcements is that very soon, you will be able to see and interact with metadata in the context of Teams - bringing the rich metadata you get in SharePoint everywhere you interact with a file. I think that investment shows that metadata is still really important!
