With advancing age, I find people rarely, if ever, truly change. Apropos, they simply become more efficient and skilled at hiding their true nature whilst applying it still to an even finer degree of effectiveness.

For counterpoint, see the well-known Jobs video recanting the Microsoft/Apple feud, just after he regained control of Apple. His views did change.

A fair assessment. I, however, would take care to separate the nature of a person from the views they find acceptable to express in public; especially those views for which there is considerable contention and/or ambiguity.
