My hypothesis is speculative. I think what we call "shit work" is in fact something that is less creative and as such is likely to be subject to automation/algorithmization.
In other words, with the right tools, platforms and algorithms you have less shit work to do.
A few things that can be considered "external bureaucracy", such as accounting, patents, legal stuff etc, that are kind of beyond your control, so they should simply be outsourced. For bookkeeping, hire a company. There will be some amount of interaction with them of course, but that itself shouldn't require full time involvement. I did that for one of my companies, worked OK for us.
