Hey Mike thanks for visiting and commenting! like yourself and @steemitadventure I see it has a 2 pronged fork - one really good and the other really bad. Both of these possible futures are as you said related to human nature. Yes there will be a human element for some time to come in the workforce but it will continue to dwindle as time tolls on.
Those that continue to work after the UBI is introduced will likely be paid much higher than those just on the UBI. In case you hadn't gathered from my Twitter feeds (thank you guys for following me there too if you do) I am a big science buff and am always looking at the latest technological developments and as you say @mikepm74 the future is going to be very interesting indeed!
