I think bootstrapping might be impossible for non-programmers 14 years ago
I agree with the premise that there is alot of changes that have to be made as you move along and iterate, but if you have a skill you can bill at a higher rate than you can hire a programmer at, then you can totally iterate. I have development skills, but also run a consultancy where I can net higher hourly rates than it costs me to hire top tier developers. So alot of times is more expedient to hire them and focus on running my consulting business. There are multiple paths, but I have seen with some of my clients they need to have deeper pockets or ongoing revenue from which to iterate out of.
