@amanda @futurebird He's wheelchair-bound and doesn't get out much, so when I visit he always has a lot to talk about. We almost always end up talking about some topic that's been on his mind. Often it involves historical facts, and he sometimes pulls up a search to check some year or other factoid. I tend to double-check on my phone. I'm waiting for a good teaching moment, but there hasn't been enough instances of this yet since AI "took over". It's really hard to change topic with him though.
