If people still want other people to do things for them, accounting isn't going anywhere. It has already been invented. We don't have to un-invent it. But, if this our future, then humans remain relevant, so there is no concern about job loss or anything of that nature.
If, however, some future plays out where people aren't needed to work anymore, there will simply be no need for trade. The magical AIs, or whatever it is that someone has dreamt up that they think will eliminate the need to hire people, will provide instead. You only need people to buy things from you if you need to buy things from them as well.
