As you should know, robots are very rapidly taking over almost all sorts of manufacturing processes that used to be done by humans (like making cars), as well as driving cars. But those robots are very, very stupid and do only and exactly what they are told to do, very accurately.I believe that artificial intelligence is a long way in the future, if it will ever happen,and I'm not worried about it.Arduino can be a great introduction into the difficulties of programming a robot. Try to program one to direct a toy car to navigate a course, and win a race -- it will take months or maybe even years of your time.
You might be surprised how similar "real world " and hobbyland can be. No..nasa probably isn't using arduino, but asimo might. But also probably not. Bottom line is they use microcontrollers for minor tasked, and those are commanded or guided by computers managing the bigger picture. As a lifelong hobbyist, I got a job in large commercial building controls (large buildings are like big stationary robots with automated everything behind the scenes) and expected to be way behind everyone else - turns out everything is exactly like hobbyland - there's just more of it in one panel so it looks intimidating at first. Still...just instead of one or two microcontrollers and IOS there is rows and rows and each one is still one of the varieties I've used in my garage. Maybe not by brand, but it's all the same.You want to step up from arduino? Get a raspberry pi and learn to interface and control multiple arduinos/other microcontrollers from that.

An Arduino can control many other Arduinos, too. No RPi needed.As for the RPi, it is a step up in some ways, but it's not always better to use (i.e. controlling servos, limited IO compared to Mega, no analog inputs, etc).
