Agreed, there will be more people online. And we will be having web 3.0 or something.
But still people will prefer offline jobs- definitely!
Why wouldn't people prefer jobs online?
I think people are going to start coming online for more and more things. I think soon you will be able to get all your groceries and neccesseties sent right to your door. This would reduce our dependancy on oil! Since online jobs will mean very little cost to get to work, I think people will actually prefer jobs online.
There will be a higher demand for work, but because of the amount of workers it will be hard for us to compete against eachother. But it's definately worth a gamble, that's why I'm making my web empire NOW before it's too late
