Big data will replace the need for 80% of all doctors
Those two are scary
Yup, quite, but I tend to believe that the trend of jobs being automated only to be replaced with new information technology/creative/human interaction jobs is going to continue, as it has for the last century or longer.
It might be difficult to imagine a future where there are enough jobs to keep everybody occupied, but then again, it was probably the same when automated manufacturing made line workers largely obsolete; computers made typists obsolete; farm equipment made much farm labour obsolete, etc.
What the missing jobs took away in jobs have been largely offset by improved standards of living for everybody, better infrastructure and an economy that provides a stronger social net that fewer people fall through; high-paying technology jobs that power even more progress for humanity. We're living in the most prosperous, peaceful, socially equal period of human history, and I (along with many experts) only expect this to get better.
Interesting Ted talk that talks about this: http://www.ted.com/talks/peter_diamandis_abundance_is_our_fu...
Edit: Quoted section of OP's comment that I was replying to.
But I am wondering what kind of innovation would get rid of 80% of lawyers!
Now, THAT would be very welcome !!
I believe it is true, but more for dieting reasons than anything else.
Right now this quote is still true:
"The food industry doesn't care about health, and the health industry doesn't care about food".
I hope big data will change that. The future is keto.
Right, because if you don't have a job, you don't deserve to have a house, a car, or self-respect.
Also, if you're born a serf, you're bound to a manor, and smallpox is God's way of reminding you that all humans are born in a state of profound sin.
