I've coded in some esolangs, but never one that's nondeterministic - seems a nightmare! The design has the hottest paths most likely to degrade so I guess the idea is to have redundancy in your code?
The simple hello-world example is already 2002 lines long, so "production-ready" Furchtbar must be enormous.
I disagree, they have it working on the nRF52840 (which is new and supports new things like NFC and Thread/Zigbee). This means people can start developing features against that chipset.
Hardware doesn't mean "production-ready model".
