So take that they are "transforming how health professionals and patients interact with technology" with a massive grain of salt, even if all germany used it every single day you could run the entire operation on a medium ec2 instance with a single RDS instance.
Bleeding edge stuff.
The tl;dr here is they also don't want to have to pay to outsource their support staff, so they're paying openai or someone else instead.
So amaze. Much wow.
