I'm not really too concerned about AI at the moment since General AI is still a few years off, then i'll start to worry. I do feel specialised AI will begin to grow rapidly in the next 5 years with the amount of money and projects in this sector and the trade off is reduced labour force so more people will be out of work while few people with specialised skills will have work.

It may start small like people who work at a store as a cashier but it can grow exponentially and anything that has set rules and logic can be taken away from humans. You'll see things like accounting fall away, i mean why would we need them if we have AI and Blockchain?

You'll see things like medical doctors reduced since machines can scan you and administer dosage and even go as far as simple operations. Its a scary thought, thinking about how our dependance on machines will continue to get worse over time.

Who knows we may even assimilate with them one day to form something new a bit science finction-y i know but i'm not putting it past the human race
