RE: World War III: the battle of algorithms?

I work in a senior home in Austria. Many people there fought in WW2... It's sad to see some of them now have dementia and live in the past, believing the leader of Germany was their savior and did good for the world. There's a 95-year-old man who is not forgetful. Every time I enter his room, he salutes like they did in Germany back then. He always talks about how the world would be better if Germany had won. It's difficult for me to listen to this. I'm a foreign girl in a country I wasn't born in, and they never accepted foreigners living in their country. What bothers me the most is that he is really nice, but he loves to talk about those times and how he fought, flying his airplane and dropping bombs 🤦‍♀️🤦‍♀️🤦‍♀️ So no, we didn’t learn anything…
