You clearly never used Taligent and OpenDoc. They were innovation by committee and completely revolting. You can read the introductory Taligent tutorial here:

As for Hypercard... it wasn't Apple's innovation but Bill Atkinson's (he designed and wrote the whole thing). Once Bill left (6 months later), no one else was really able to manage the codebase and it rotted for a decade or two until it was finally cancelled.

I've really been enjoying reading Brent Simmons blog about his efforts to get Frontier running on modern macOS:

I suppose that Apple Dylan was similar to Frontier in the sense that they were programming environments built around an object databases. Frontier was a shipping product though!

Back when they actually had an R&D department.

Hypercard should not be on that list, it was succeful despite official neglect.
