Oh my, Justin (from my favorite newsletter platform Buttondown) nails it here:

Customers make for good historians but poor futurists, and certainly they won’t do the hardest and most important job of identifying your leverage points for you.

That was your shot. Here’s your chaser:

None of this is to say you shouldn’t talk to customers: you should! But it should be neither the first nor the last step in your process: if someone needs to talk with people to figure out what to build next, it means they have insufficient vision; if someone needs to talk with people to figure out if something is truly ready for GA it means your org has insufficient conviction and process.
