I agree! iOS, iPadOS, and WatchOS all emerged with a view toward maximizing energy from a very small battery (by comparison with MacOS). Applescript emerged at a time when computers had continuous power. The only real constraint was memory. When Apple invented iOS for the iPhone, it was clear that MacOS and iOS would eventually blend, but not without efficient gains on battery to make this possible.
Applescript, by contrast, was simply constrained by active memory, and longed for the day enough would make it possible to have programs “talk” to each other (anyone remember “AppleTalk”? and eventually “Bonjour”?) Those were the device-equivalents of what Applescript sought between “Applications”, “Files”, and “Workflows”.
But coding in iOS, iPadOS, and WatchOS emerged within an ethos for making sure nothing talks to each other for very long (to preserve power and reallocate memory). And assurances for specific permissions would be required for each request (only single-point access for a temporary period of time and with an end-user approval button). That added security constraint is Applescript-averse. Applescript doesn’t feel like Applescript when every new ‘tell’ statement requires a new end-user approval “Ok”. These are the difficulties of trying to re-spawn Applescript on these OSes.
For MacOS, Automator was the answer to make automation more accessible to the masses. It did some good, but could never replace the more custom workflows Applescript pros know and love. This is because the power and passion for Applescript comes from what becomes possible across applications, files, and workflows. It is like conducting a coding symphony! This is why there is so much residual passion for this programming language and why so many of us don’t want to see its support atrophy.
“Shortcuts” is the emerging Automator of iOS, iPadOS, and WatchOS. It represents where we are on that arc of sufficient power and memory for automation on these devices—currently only for use with a few apps. Currently, the developer training and focus is for these OSes. As a result, “Shortcuts” (iOS Automator) is the natural path. But, for those of us who love Applescript on MacOS, who appreciate making it sing across apps, and who know its value once the efficiency constraints are overcome, we long for the bridge which makes pro work on Apple devices such a delight. But the arc for sufficient battery life, workable security constraints, etc., are just not there (yet) for Applescript on iOS, iPadOS, or WatchOS.
But what about VisionOS?
It seems to me that VisionOS is a natural landing for Applescript. VisionOS is absolutely incredible and while it may not be ready for 8 hour workdays, the workflow made possible by its foundation is truly revolutionary. Perhaps VisionOS is a good place to put the focus for the Applescript petition? The battery life is significantly better than iOS, iPadOS, and WatchOS. Could VisionOS be a productive gateway to begin thinking about the blending of MacOS and these battery-sensitive, app-siloed ways of thinking about the entire experience? Does Applescript on VisionOS make it possible to smooth out the experience in ways which have not been considered? It certainly seems like a fantastic device for conducting a symphony! 
Here’s to the crazy ones!
