Some more interesting background:
The founders originally built Shortcuts as a separate startup. From memory I think both were under 20 at the time. They were acquired by Apple, and turned their startup into a default application that people actually like.
One of my younger teammates got into programming thanks to their app.
you can see where it all started back in 2014: https://www.youtube.com/watch?v=49JJnJ2i4oc
Are you looking for a real answer or is this some weird defensive Android thing in response to someone describing the existence of an Apple feature?
A similar app has existed for Android for about 15 years at a time when nothing like that existed for iOs. It was actually used by Google to showcase Android's potential for automation in contrast to iOs which had nothing like that at the time.
Presumably if OpenAI is dog-walked/locked out of these by Apple at some point, they would be stuck in the Chrome/Chromebook feature jail. My guess is this gives OpenAI a team to put in charge to give them a chance to wedge themselves into the OS before Apple changes their mind or puts scare-box dialogs everywhere.
Either that or there's nothing so complicated and OpenAI just wants to re-build this stack inside ChatGPT as quickly and well as they can.
My favorite is an automation that triggers when I turn on my motorcycle helmet's bluetooth module, it checks the time of day and starts playing my favorite type of music for riding at that time - hard rock at daytime, EDM/synthy music at night.
It's a bit surprising to me that, say, Zapier hasn't skunkworked up something like Shortcuts that could be crossplatform. It's not immediately their core competency but being able to roll out low code UIs across employees of a phone through that would make a lot of sense.
The unfortunate thing with iOS is that while there's some secret stuff with deep linking ultimately less stuff is exposed than what one might entirely want. But I _was_ able to make a "fake" Find My for my bluetooth headphones in about 5 minutes (bluetooth disconnect -> record lat/lon into a text file on my phone) and that was fun.
