>If you need to wait YEARS to hire someone with some specific experience, I can guarantee that you really didn't need that person. You're doing this just to check some specific artificial goal that has little to do with the business.

There's a difference between "critically needing" and "would benefit from."

If you can find the specialist who's done what you're doing before at higher scale and help you avoid a lot of pain, it's awesome. If not, you keep on keeping on. But as long as you don't start spending too much on the search for that candidate, it's best to keep the door open.
