Is it? Just opened it on Windows 10 and it opens instantly and uses 23MB of RAM which is rather low for a modern application. Calculator is also fully open source now.
Seriously, is your post satire or you think 23 mb for a calculator app is good?
Whole windows 95 (including a calculator app) fit in 16MB of RAM. In fact even less, since you could run few programs on top of it too. Connect to internet even..
23MB for a modern calculator in this day & age when many apps are written in Electron/EdgeHTML/web technologies is pretty good
Do people even use uTorrent anymore after the advertisements were brought in? I use qBittorrent when I need some Linux ISOs and in an idle state it's using 20MB which isn't bad either.
The ancient version of utorrent (before ads) works fine.
