Interesting, I haven't. Is it hyperbole? Or are you underestimating it? The heart of a car is the engine, but just the engine alone doesn't get you anywhere...

It is not hyperbole. I'd say it is in the area of microservices and data crunching. Where 90% of the code is about ingesting and forwarding.

Depends on your viewpoint. For some a car is just 4 wheels that take you somewhere. For a mechanic it is a world full of valves and pipes.

But I hope not every team builds a car from scratch.
