Most people are not Steve Jobs, and do not have such a vision. Or the ability and capital to see such a thing through to the end. Steve Jobs also had a number of visions that didn't work out so well too - he learned and interated from them.

Thus, for most folks releasing a product and getting to market/revenue is more important than anything else. Then iterate from there.

YMMV of course. But the older I get, the more I realize "just get it done" is far more important than almost any other metric there is. There is a ton of navel gazing in tech that provides negative value. If I had released some of the things I worked on in the past vs. carefully designing and polishing them, I might still be working on them today. Competing products have maybe 50% of the "quality" of even my prototypes of 10 years ago - but they exist in the market and are used every day by customers to generate income.

That's the test part, is it not?
