If only it was that simple. Startups are not successful if started by employees. You have to be 100% focused on the business and have the passion and commitment to make it work.
I'm not bored of it. It pays the bills. I still learn stuff all the time.
Point is, you're right in the sense that you probably want people who have good domain knowledge. However, there's nothing special about technical founders without that.
I'd even say most times their skills at getting an app out quick and fast (and good) are probably not that great, which is important for startups.
i know this is impossible for you to believe.
so in other words, the aspect of 'business' that your particular skill covers is probably about 1-7% of the entire domain.
