IMO going from engineer to musician is not a change of preferences, only a change of the strategy you follow to satisfy those preferences.
I would say about a person for whom this is accurate that they didn’t really care about engineering, or then music. But there are different people who do care about engineering, or about music. There is a difference between the people who should be described as only changing their strategy, and those who change their purpose. I was referring to the latter, as an example analogous to changing one’s revealed preference to one’s endorsed preference, without being beholden to any overarching ambient preference satisfied by either.
IMO such “change of purpose” doesn’t really exist. Some changes happen with aging, some changes might be caused by drugs or diet, but I don’t think conscious reasoning can cause it.
