alt Hacker NewsI think you probably misunderstood me.
You can use a better tool than someone who is using a worse tool, and take their customers, because it will be easier to solve the problems better and faster than that someone-else. Lisp is a great tool, but it doesn't help you if you're the tool: You still need someone with a problem who can pay for a solution, and they need to like you enough to pay you for that solution. If you need to hire 30 people to figure that out, Lisp isn't going to help with that problem.
And it's not fast: Lisp is not a get-rich-quick scheme, it's a tool that you can learn how to use to make other tools, it's a tool that is difficult enough to use that you will need perhaps years of experiences in order to use effectively, it's a tool so advanced it might seem like actual wizarding magic just watching someone screencast if you don't know what you're looking at, but it's still just a tool.
I am literally asking you to show me what you are talking about.
Who retired early? What did they make with Lisp? Do you have a link to that thing they made? Was it actually something special about Lisp or did they just happen to use Lisp while making something that could have just been as easily - or more easily - done with something else? Is that real-world, specific, material outcome replicable by other people and they should know about it?
