You are being pedantic, but I’ll play along. Absurd has multiple meanings. It can mean nonsensical, but it can also mean utterly ridiculous or silly. Under those other meanings I believe the pop-star-physics-professor still qualifies.
It sounds pedantic, but "absurd" is fundamentally different from "rare". A lot of baggage comes from flagging something as absurd, instead of just unexpected or uncommon. Winning the lottery isn't absurd, having 3 pairs of some chromosome isn't either, and being a successful pop singer with an academic background isn't either, it's just rare.

Maybe not so absurd.
Also, Todd Rundgren used to be a registered Apple developer. We'd see him moseying around the WWDC, every year.
