The hardest lesson I’ve learned in making products is that other “little” thing that affects the success of a product - Distribution. Build it and they will come The classic fallacy and naive fantasy of anyone who starts off on the R&D/Product Development/“tech” side. Make the iPhone and they will line up  at your stores sacrificing nights of sleep and days of comfort, to bask in the glory of your creation. Except that doesn’t happen.
“My mobile OS uses differential space-mapping to provide a whole new level of privacy, everyones worried about their privacy, it’s gonna be huge” Except it’s rarely huge. Getting huge requires convincing a huge number of people about the value of your product. Convincing a huge number of people is a very different business from making a thing that can be huge. Good product without good distribution is like winking at a girl in the dark - its doesn’t even matter that you went to the gym and look like Ryan Gosling, that you can debug a VR headset with your left hand while reciting the works of Murakami. Your brilliance is irrelevant, if no ones sold on it. Neglecting one for the other is leaving Yin for Yang. Bad idea.
