In GE they know what is the future of work and there are probably no human workers in it

What else can it build? ... a world without work ...

Here is a new promotional video from General Electric where they show a "factory" with 3d printers and robots. Video ends with the question "What else can it build?".

Once upon a time, a factory built one thing. Now, a factory can build as many things as there are people to imagine them.
GE works on things that matter. The best people and the best technologies taking on the toughest challenges. Finding solutions in energy, health and home, transportation and finance. Building, powering, moving and curing the world. Not just imagining. Doing. GE works.

I see human workers in this video as decoration and corporate marketing

Theoretically there could be a large robotic factories in internationals waters without any workers and in tax-free regime ...
Humans are not even needed for design ...

Will it cause global dystopic favela or utopia of technoprogressive heaven ... or both like in Elysium ...

Another question that comes to my mind is can new factories even be called "factories". They are basically just a one big large fabrication machine ...

Future will be interesting ...
