It’s not just like jpeg with extra channels. It’s technically far superior, supports loss less compression, and the way the decompression works would make thumbnails obsolete. It can even recompress already existing JPEGs even smaller without additional generation loss. It’s hard to describe what a major step this format would be without getting very technical. A lot of operating systems and software already support it, but the Google chrome team is practically preventing widespread adoption because of company politics.

We don’t even have gates. Most people just pay for their tickets. Sometimes there are ticket inspections - if you get caught you’ll be fined. Way cheaper than enormous infrastructure for every entrance that just slows you down if you have an annual ticket for example. https://youtu.be/kq-X25pH1XQ

How about a real desk 🤣
