I am pretty sure the sign should read "you have to be at least this much of a nerd to buy this keyboard" :)
Or maybe "you must be at least this far down the rabbit hole".
If you're a total keyboard nerd then you will have formed Opinions on which switches you like based on the sound they make and the feeling when you hit them. Follow a keyboard nerd community like /r/mechanicalkeyboards or /r/keebgirlies and you will see people constantly posting videos of them typing on their new keyboards to show off its "creamy thock" sound. There's like a few dozen different switches out there and some keyboard nerd shops will sell you a little block of a bunch of different switches with keys on them solely for you to poke them a lot and decide what you like. Or you could just take the default option.
If you're a total keyboard nerd then you'll have a copy of the QMK source set up so you can make edits and shoot it to your keyboard with one keypress. Or an even more esoteric open-source keyboard firmware package because you have Opinions about that too.
Picking keycaps is easy: what color do you want them to be? Do you want a few extra keycaps in a contrasting color to mark the home row, WASD, various shift keys? Keys with astrological symbols, abstract designs, or cartoon characters instead of letters? If you're a total keyboard nerd you are probably fine with keycaps with no letters on them because you have a complex setup with a lot of layers. Maybe you want to go even deeper down the rabbit hole and buy a transparent acrylic key with a little sculpture in it. Maybe you care about the shape of the keys, too. There's a bunch of different possible profiles for the tops of keys, because that contributes to the feel too and some people like to have Opinions about this.
What’s slightly annoying is that the ergonomic space is almost all mechanical. I have zero interest in that aspect, I just wanted switches most like my MacBook.

It's a really deep rabbit hole!
