I don't know him yet. Are there some talks you can recommend that would be a good starting point?

That must of course be "Haskell is useless" https://youtu.be/iSmkqocn0oQ?si=IkTHHdH1423tOVvz

But apart from that, his enthusiasm can even make the mseemingly most boring topic interesting.

I'd personally start either at "the story of Haskell" Escape from the Ivory Tower https://youtu.be/cOqxiS-WN1w?si=1iXpGE7cJZa4tbbJ Or something more recent, about Epic's Verse https://youtu.be/OJv8rFap0Nw?si=OE2mUllQfLmV29Bk

And if Haskell isn't your jam, maybe Excel is more to your taste? https://www.youtube.com/watch?v=jH2Je6wUvPs

It's only the most popular programming language in the world.

And it's functional, too!
