Things programmers believe:
People only live at 'official' addresses
People have exactly one address
No one homeless ever used a computer
People never change their country
No one has a mobile phone from one country but lives in another.

No one lives in one country but works in another.
No one works more than one job at a time.
No one is unemployed.
Humans have exactly 2 names.
No one has two names at the same time.

Everyone has exactly one smart phone. It's on and connected all the time. It's number never changes.
No one ever loses their smart phone, laptop, or desktop.
No one ever changes their gender.
Everyone's anatomy is predictable from their listed gender.

No one lives in a place where saying something could be dangerous.
No one needs to conceal their gender or name.
No one is hated just for who they are.
No one has a real investment in any of their accounts.

What have I missed?

Names are at least 3 characters long. Andrew Ng disagrees.

Only humans have accounts. Just ask IBM or @PomatiaTheSnail
Only corporations have accounts.
No one is both a vendor and a consumer on a 2 facing platform.

Everyone lives in the USA.
All internet happens under US rules.
Currency works like it does in the US
Everyone has a credit card (not true for either Netherlands (iDeal bank transfers) or India (QR code based proprietary payment solutions)

Every entity is a person or a for-profit corporation. No one is @yayfrens , @PomatiaTheSnail , @ManCity , @PrologSwi etc.

Every country issues ID, which every person has. Obtaining ID is never problematic.

Everyone is on a fast internet, reliable internet connection and physically able to type fairly fast. It's ok to put time limits on interaction.
