If there is 50% unemployment, it will be because govt has made it impossible to create/do work.

You seem to believe that just because what some people currently do will be replaced, that they will be incapable of doing anything else of value.

I honestly cant understand that.

Though I do think it might be the case that we develop a much larger "shadow economy" where a great portion of economic activity goes "off the books".
