Recently I read somewhere that mining has become less efficient, as people are illegally mining. There are many technical changes that are going to be implemented for mining. If this is true.

Everyone in the world will find a job unless and until everyone is skilled at the same level. Skill is an important aspect in getting a job, be it technical or other. Education also plays an important role in this, if every person is being educated in the world to get the required skill, then everyone will get a job in the world.
