I actually don't understand what problem this and other API gateways solve? Let's say I have a bunch of services calling each other. Which I already do... Why

  This is a service mesh like Istio not an API gateway, it's mainly used for automatic and transparent service discovery and load balancing where client and server service endpoints don't have to worry about that, also other features are automatic handling of failure when one server endpoint isn't responding, traffic management, securing communications between services, enforcing L7/L4 kind of a firewall between services, telemetry, etc..., you probably don't want to use a service mesh like this until your software architecture gets really complex
