What I've gotten from the comments is that you guys don't think it's smart to take an inside-view. That's a separate argument in itself, but what I'm trying to do in this post is to take an inside view, so please take that as a given and comment on the components themselves.
I agree with VAuroch that this won't help much, because in general taking the inside view is a bad idea.
But if you want a few examples of places you've gone wrong - both getting a good idea, and executing a business, any business, are much harder than you imagine. For example, you wrote:
"Failure to think specifically about benefits." "The big issue here is the first bullet point. As spelled out by Eliezer's article, people are horrible at thinking specifically about the benefits that their idea will bring customers. They're horrible at movin...
My motivation behind this post stems from Aumann's agreement theorem. It seems that my opinions on startups differ from most of the rationality community, so I want to share my thoughts, and hear your thoughts, so we could reach a better conclusion.
I think that if you're smart and hard working, there's a pretty good chance that you achieve financial independence within a decade of the beginning of your journey to start a startup. And that's my conservative estimate.
"Achieve financial independence" only scratches the surface of the benefits of succeeding with a startup. If you're an altruist, you'll get to help a lot of other people too. And making millions of dollars will also allow you the leverage you need to make riskier investments with much higher expected values, allowing you to grow your money quickly so you could do more good.
A lot of this is predicated on my belief that you have a good chance at succeeding if you're smart and hardworking, so let me explain why I think this.
Along the lines of reductionism, "success with a startup" is an outcome (I guess we could define success as a $5-10M exit in under 10 years). And outcomes consist of their components. My argument consists of breaking the main outcome into it's components, and then arguing that the components are all likely enough for the main outcome to be likely.
I think that the 4 components are:
The Idea
Your idea has to be for a product or service (I'll just say product to keep things simple) that creates demand, and can be met profitably. In other words, make something people want (this article spells it out pretty well).
