Reminds me a bit of studying the Industrial Revolution. Everyone then was afraid of being replaced by a machine. Did that happen? No it didn't.
I reckon the same will occur here. There are jobs that haven't been invented yet. Some will disappear and other will replace them. People will need different skills.
Also for a country like New Zealand some of this automation will be difficult to implement, here I'm thinking of self drive truck, taxis buses. The technology is currently based around dense populations where it will work very well. I'm less sure how some of it will stack up in many parts of New Zealand where we don't have dense populations.
For quite a while at least humans will still be cheaper. One good example is pilot-less aircraft, the technology and the manpower to run that technology is more expensive than paying pilots to sit up the front.
