Automation can absolutely do manual labor. How do you think cars used to be made in the past? By workers manually attaching the parts together. Today however we have giant machines that perform those tasks.

It's only a matter of time before other forms of manual labor are automated. It won't happen all at once, but gradually.

I said mental labour, not manual.

Yes, most physical labor may be automated... eventually, a lot of that is still fairly far off - we don't even have completely automated farms yet.

I'm more talking things like development, writing, design, marketing and sales. Things like that we'll probably always want some human touch to, even if it can be machine assisted in some ways.
