I always found it funny, the idea that age or agism should in any way stop you from achieving cool shit in business. Entrepreneurship is a jungle. Your customers, largely speaking, doesn't know your age or gender or whether or not you went to an ivy league school or anything else. Some career directions certainly do depend on that stuff, but that's mostly because they depend on other people for advancement. But building products is only a competition against forces that pull down quality, not a game of gatekeeper-signaling. If you want to succeed in business, you can either let that stuff affect you, or you can just build something that people buy and prove everyone who says there are fundamental barriers wrong.
