How? 1000 engineers x 1000 LoC/each = 1M LoC

Why? If you have 100+ engineers at any given time, shipping features over a period of a few years, you'll hit 1M in no time.

It sounds like a lot, but it really isn't when you consider the amount of people working on it.

Now whether or not you can build the same thing with less LoC, probably. But it's not like it was built from the ground up with every piece of functionality planned out from day 1, so there will be inefficiencies.

Comparing it to Linux is pointless. Platforms should be relatively stable, products are ever changing and the shelf-life of the code is sometimes measured in weeks/months.

The app is the size of a Debian installer with dozens of executables made over the course of 50 years.
