The process of developing capitalism has taken millennia and in the last few centuries has had far more intellectual horsepower put into it than developing phones. Lots of iterations have been tried, it can't be compared to a beta product at all. The major problem we have on that front is people keep trying to regress backwards to models of organisation that have already been tried and are well understood not to work effectively - because almost nobody votes based on historical learnings.
Once we have >100 years experience in building phones there probably won't be annual upgrades any more either, it'll be like-for-like replacements.
What do you count as iterations? There's never been a violent throwing out of capitalism to be tried with a different version of capitalism. The throwing out of capitalism has been to replace it with something else, not more capitalism. And has the horsepower been put into developing capitalism, or has it been put into making more money for the people wielding it, rather than developing the best system there could be?
Why does it have to be violent? Every election heralds a slightly different version of capitalism based on the regulatory and tax priorities of who is now in charge.
Edit: Think of it in software terms. Version 1.1 or even 2.0 is normally not a complete rewrite of version 1.0, instead it's an iterative set of changes. Rewrites are often considered to be a bad idea.
Capitalism concentrates power to the top; those powerful people are the ones who have had the power to reinvent it so far. E.g. in 2008 when the Fed began QE Infinity, which never ended.
