Add me to the list of "saw nano banana pro, attempted to get an API key for like 5min, failed and gave up." Maybe I am a dummy (quite possible) but I have seen many smart people similarly flummoxed!
You can walk into a McDonalds without being able to read, write, or speak English, and the order touchscreen UI is so good (er, "good") that you can successfully order a hamburger in about 60 seconds. Why can't Google (of all companies) figure this out?
