If everyone gets told to forget about mining, who will do the mining until 2114? coz the current miners will be all dead by then

Whoever comes after I guess the current miners, it will likely me more like a business soon enough.
So people will go to work at the mines, work as maintenance and get paid a wage, while there will be heads of the company on top reaping the benefits and deciding what changes to make to the company direction.
Is it 2114 or 2140?
