I am a senior software engineer that mostly works

I am a senior software engineer that mostly works on classified military software. The notion that someone could recreate the entire functionality in 1000 lines if coding as well as the statistics gathering, repotting, notifications, etc is preposterous. Sure, one could make a video worth an area to click on that jumps to a url. But that is a tiny piece of the functionality obviously. Also it would not be scalable, and where is the database to h,d all the user accounts, passwords, settings, client lists, etc? Sorry, anyone who claims all of that at the enterprise level can be done in 1000 lines of code does not know what they are talking about. .
