Just think in an imaginary world where you and a few other BF posters prefer to dwell...
when robots do all of society's work, no more work related injuries or fatalities!
when robots do all the work at home, no more injuries or fatalities from doing work or projects at except for falling out of a hammock while taking a nap.
best of all when Virtual Reality devices are perfected there will be no reason for people to travel anywhere, everything worthwhile can be experienced at home and there will be no more need for human transportation and its associated costs!
