To put it in perspective, if you had the brightest idea to solve a pressing real-world issue, you’d still need millions, if not billions, in up-front capital. Once you’re operational, the amount of expenses you’d need to run your business will eat into your revenue aggressively. Then, it takes a long time to innovate and react to industry changes, with complex mergers and acquisitions presenting themselves as solutions to moving quickly. And all this at the risk of becoming a giant, centralized, single point of failure.
