In fifty years from now ,in many branches of the industry,agriculture and services, machines will replace men on tasks held now by the humans and a lot of jobs will disappear.Among them ,certain types of welders, train conductors,some shoemakers,smith ,bus drivers,taxi drivers
Also new jobs will appear,like different machine supervisors, advisers, different new healthcare practicians( maybe brain relaxation specialist ), command center operators,drone operators, software creators, IT engineers.
The trend goes towards implementation of computers and artificial intelligence in every possible way,if economics and benefit occurs.That will lead to millions of unemployed people ,especially those without skills.
