Ridiculous, in your view.
I would say, if such a modern application development environment can run on such an old computer, that is remarkable!
If Xcode runs at reasonable speed on a 2014 MacBook Pro, and is usable, then I am surprised, but good luck to you.
To speed up the installation in future:
Try downloading and extracting on a more recent/faster Mac, then transferring the app to your MacBook Pro
Add more memory (if possible?) to (max out?) your MacBook Pro
Upgrade your hard drive / ssd to the latest/fastest ssd that your computer will support
