I'm sorry, but, no, you're not even close with the size comparison. Office 2021 is 4gb, libreoffice and office 365 are smaller than that. The cheapest bluray will hold 25gb.
Obviously office programs have not become easier to run (with libreoffice maybe being an exception), but processing power has vastly outpaced whatever new requirements they've gained.
Shit like teams needs a supercomputer to run well, and will be slow on everything else. There is no point in buying a top of the line laptop just to keep teams or a badly made website from lagging.
People haven't seriously used floppy disks for twenty years now.
