Aside: that phrase "someone who is trying to help" makes me wonder whether you know that _this_ someone is a Nobel laureate (shared with Veltman in 1999), as he casually mentions in the text.
I did read it so yes I did know. I just feel like most active researchers would be able to point people in the right direction, so the fact that he's a Nobel laureate wasn't particularly relevant.
Nobel laureates don't typically cease research after receiving the award. He's still active.
