User level: Level 1 (0 points)MacBook Air (2022) Golden Gate 27.0.1 - iCal changes have made it almost unusable for me. How do I roll back to the iCal view/settings/features before this latest update? I want a calendar; I do not need AI assistance. This is nonsense.

You cannot selectively revert one macOS application to an older version. Most native macOS apps, including the Calendar app, are installed on a sealed, read-only volume that can only be modified by macOS itself.
It sounds like your main issue is with the Apple Intelligence features. Apple Intelligence launched with macOS 15 Sequoia (and iOS 18), and since then it has become progressively more integrated with macOS (and iOS). On macOS 26 Tahoe, there was option to turn off Apple Intelligence (though doing so did not remove the 12-14 GB of local storage taken up by Apple Intelligence features).
On macOS Golden Gate, the toggle above has been removed, and Apple Intelligence is even more tightly integrated with macOS. Consequently, it is very difficult to turn off. Long-time forum member etresoft has written a helpful tip on how to Turn off Apple Intelligence in macOS 27. The title is somewhat misleading, Apple phrases it more accurately in their support article:
Turn off and restrict access to Apple Intelligence features on Mac
As Apple states, you can turn off and/or restrict access to some features of Apple Intelligence, but you cannot turn off Apple Intelligence altogether.
Apple Intelligence features can be restricted in a more comprehensive way by using a declarative configuration, but that requires device enrollment (i.e., management of the Mac with MDM) and that is beyond the typical processes with which most users are familiar. However, there is a script called Remove Mac AI that is available to execute those functions as a local Profile via a terminal command, if you are comfortable using it. At least one long-time member here has done so without issue. Use it at your own risk.
You can also share your opinion with Apple:
Note that the current version of macOS is 27.2. Based on your post you are running an older version, so the first step is to update your Mac to the current version.
