Something I&#x27;ve been thinking about recently: does anyone think Slack followed Thiel&#x27;s advice? It entered a space that already existed (didn&#x27;t go from 0 to 1), with several competitors, solving a problem that was widely known (email is a broken way to get work done). Yet it&#x27;s becoming a monopoly and will likely be a very valuable business. It seems like there can be tremendous value in making something really good when the existing solutions are not good, and that creating an <i>extremely</i> valuable business doesn&#x27;t require doing something entirely new.
