In reality, I'm a strong supporter of everything above. Maybe we can really provide people better jobs by delegating repetitive and boring things to machines and allow everyone to do something they enjoy to earn their lives.
One can dream, I guess...
Machines are anything but reliable. They need constant servicing and maintenance and still break entirely
When you are not budget constrained, and building things for businesses, a little overengineering goes a long way.
I have a Xerox 7500DN color laser printer next to me, and it's working for more than 20 years at this point. It has gone through a lot of spares, but most (if not all) issues are from parts wearing down naturally. Nothing breaks unexpectedly on that. Same for robots. Give enough design budget, overengineer a little, and that thing will be one hell of an ugly but reliable machinery.
When you work with real "industrial" stuff, the landscape is very different.
