>> some people who I found were really knowledgeable don't code at home How old/what phase of life were they in? I find that, in general (anecdotally), this tends to slow down for most people as they age or advance in their careers. In the beginning, we have time/energy, desire to learn/advance our skills. As these tendencies reduce over time, only the more hard-core/passionate remain. So if say it's depends on this spectrum when asking knowledgeable programmers if they code at home. They might have already gone through that phase.
