“Lisp doesn't look any deader than usual to me.”—David Thornley via http://www.paulgraham.com/quotes.html

The actual graphs on the Tiobe can empirically show it's getting deader.

Lisp was around decades before "Tiobe", and will be for decades after.

That wasn’t the point. It’s losing popularity. It’s been in a downtrend that has never recovered. It’s only getting more and more esoteric.

Maybe it’ll come back in fashion one day.
