It's a bit insulting to assume that having more than a dozen tabs open must be "disorganized", especially in a context where it is likely that the power user in question is using browser extensions. Something like TreeStyleTab makes it easy to keep hundreds of tabs organized with clear, easily-manipulated structure, and lower friction than manually creating and curating bookmarks.

It looks like you're either showing off your own ignorance of tools that enable workflows you can't imagine, or you're assuming that everyone's organization methods must resemble your own habits.
