In my 40s, I feel that I don't think as fast as I used, but I do a much better job at "deep thinking" and filtering out bad ideas, which leads to a higher percentage of useful things coming out of my mouth. However, I think there is something to be said about the disruption angle; when you have experience, you could indeed miss a great disruptive idea due to the worldview you establish over the years. I think that younger people, despite their often-bad ideas, will from time to time have a great, disruptive idea that I'd filter out at this point in my life. That's why it is important, when you're young, to explore your novel ideas and take some risks by building or working at a startup.
