I live in France and I've found that having a QWERTY keyboard has pretty much the same effect, even for people who look at the keys when they type and even though my computer is set up to use the keyboard as QWERTY (so pressing any key does what the key says).

I like the way you think. This is what I told my son when he asked me why I have blank keycaps.

That was my idea, too. On the occasion where I let someone use it, they stare at it like the keyboard is intimidating them. I tell them "either you know how to type, or you don't," and that gives them the confidence to continue.

If you really want to confuse people, get something like a split ortho board or a 40% keyboard. Even without blank keycaps people at work used to be very confused seeing my Keebio Iris and they're very fun to build and type on!
