The thing is, if you use a web browser instead of a javascript engine designed for delivering DRM media (ie, chrome, modern FF), you can open as many tabs as you want without consequence. The problem is not tabs. The problem is multi-process and treating the browser like an operating system.
I regularly operate with 1000+ tabs on less than 3 GB of ram. This works because I disable javascript and look at web sites instead of run applications. I have extensions to full text search and switch between them and each tab stores it's path on the web, unlike bookmarks. And I've been saving my sessions every month since Opera 5 introduced tabs (I use a FF fork now). That covers 2003-2021.

Tabs are great. Modern browsers are bad.
