I haven't yet seen people around me switch to Linux but some are talking about switching to Linux at some point in the future, which isn't surprising when we see what Microsoft and Apple are doing.

In my case, I have been also thinking about it. My old MacBook Pro has been my Linux experiment, currently running Fedora. My current MacBook Pro is an Intel one and Tahoe (Which I don't want to update to) will be the latest macOS version possible so I will probably try a dualboot at some point.
