They can have one bit. I’m ok with one bit.
As soon as they ask for a byte, they are gathering too much information about me.
I can accept that this is a significant issue, and if knowing that I’m an adult is required for certain online activities, I’ll go along, but we all know damned well this will creep.
What ever elements need to verify who I am stay private client side, and they can have a single flag that verifies I’m what I claim to be.



I do work that I love and find rewarding, I continue to create systems I am very proud of, and I work for a company I have high respect for that makes products I believe in.
I can’t think of any work I’d do for free, those are called hobbies.
