I was pretty confident on self driving cars all the way back when it was just google.
But I think the robot/ AI stuff is coming a lot faster than expected. I worked in factories a few year ago and a lot of it is 90% there.
The real key issue is the drop in prices. Robot arms especially I seen dropping. It used to be that one robot would replace the work of 4 or 8 people. (24/7 running) so the machine needed to be a little less than that. But now its so cheap if it replaces 80% of 1 persons work it only need to be really 50% the cost for business to bother to get one. Also that cost is so low it can easily be taken as a trial that might fail but we want to see, if it works we will get 50.
AI is going to be the same, to replace someone it needs to do 100% of the work and be slightly less than a lot of people. To replace some of the work it needs to be priced less than maybe even 1 person, and we are there.
