Every corp ends up being much more intensive in the administrative side once the process or product has been standardized or reached a stable version. Isn't this the case for most businesses, including tech?
A lot of startup founders, including myself, fall in love with the idea of building technology -- but quickly learn founders are usually required to be great salespeople more than great technologists.
I figured that out from doing photography. People are like "wow you take good pictures you should be a photographer." They never go "wow you love working long hours and doing paperwork, you should start a business!"
Yes. If it's a business (as opposed to, say, a hobby), success lies in being good at the administrative side. Even something that's kinda both like Linux: every interview I've read with Linus T in the last decade or two he makes it very clear he spends virtually all of his time managing administrative tasks.
