Totally different are the specific task robots in industrial plants and now moving into hamburger flipping. There, you get defined tasks and effective movements and no strikes for living wages by the robots (yet!)
If robots were meant to walk they’d be born with legs.
They remind me of senior members of Congress!
reminds me of my party days back in the 70’s and 80’s.......LOL!
Although you could out-take some failures, you could also out-take the success.
The bottom line is that they were able to achieve the desired capabilities. Now that capability is available to everyone.
And they have gotten much better since then.
This decade, robots have successfully unbolted from the factory floor; to safely walk, fly, swim, drive and snake through pipes all around us, in many different forms.
Next decade, great masses of robots will be doing so for work, rather than testing.
Once the basic platforms are developed with human-like mobility, strength, dexterity and sensitivity, it is just a new software app for it to take over the next job - Chef, bartender, maid, landscaper, mechanic, surgeon, nurse, masseuse, security guard - whatever.
There is a threshold coming where a general purpose robot can replace an unskilled person. After that, the robots will get much better, more quickly than humans could. Specialized robots are already replacing humans at an increasing rate.
Two years after the robots in your 2015 video were so wobbly walking around, they are now more agile than many people - and improving quickly.
Here is one jumping around and doing backflips in 2017: https://www.wired.com/story/atlas-robot-does-backflips-now/
Soon they will exceed the best human athletes.
Specialist robots already are better than any human in limited tasks, like simply sprinting. The general purpose robot, that can replace the general purpose human for manual tasks, is just a few years behind self-driving vehicles.
Three to five years after initial equivalence, the average new robot will be better than just about any human. The 2020’s will see the initial large fleets of humanoid robots being fielded, and many varieties of autonomous non-humanoid robots. During the 2030’s, they will change the world fundamentally.
