Just say "no".
That's the amount of RAM on an IBM Power E980 System.
The reason I'm posting this here? Because I want people to know how terrible of an experience it is. No, not having the tabs open themselves. But the frequent app crashes and hangs. The time chrome crashed and lost all tabs (iPadOS so no ctr shift t. And it was triggered by opening a link so the "restore" button disapeared immediately.)
I do not know if anyone on Google's Chrome, or Apple's Safari or Mozilla's Firefox teams are reading this - but if you are, you should know that tab management on all types of devices - be it android or a windows laptop - sucks to say the least, and is buggy/broken to be more accurate. Chrome throws a smiley face which isn't cute when you want to actually see a number. (Fortunately kiwi browser - my designated music browser - tells me I have 700-something tabs despite being chromium based.) I cannot open the tab switcher in chrome (android) for a solid few minutes unless I want the app to freeze, or more realistically, to delete/misplace some tabs. (I.e Tabs get randomly rearranged, and the tab grouping feature doesn't help.)
You end up learning "tricks" to avoid upsetting your browser. "Don't newtab for the first x seconds, instead open a link from Google search and it'll be faster" "Don't bother typing anything at all in the search field, auto complete doesn't work until the tab-smiley comes on which takes 20 seconds in chrome canary and 2 minutes on regular chrome"
On windows browsers hog memory until the system slows to a crawl. Safari is the least terrible, despite the questionable 500 tab limit navigation is still fluid.
As to why I don't close tabs - because when you think 20 different things you want to search (thanks ADHD) and haven't read any of them, you'll want to go back later when you have time.
(Btw if anyone from any of the browser's teams is interested in seeing a live demo of this in a "real life" use-case I'll be more than happy to demonstrate what "ultra-high" organic page use looks like.)
