Not really surprised, it's the usual mistake of any novice engineer, thinking that rewriting a system they don't like is going to solve all the issues they imagine.

With the teenagers involved in DOGE under Musk it's just going to be hilarious when they inevitably fail. They just never had the experience to actually go through a complete rewrite of something that's been alive for decades... And never bothered to read "The Mythical Man-Month" because of course they are ninja rockstars 100x developers, and lessons from history and experience don't apply to them.

Really sad that their mess will do very real harm to lots of people who depend on this system working...
