Strange. In the article A138563 is described as a sequence of prime numbers that contain the substring 667. But these are obviously not prime numbers. Having a look at https://oeis.org/A138563 reveals that these are simply any numbers containing the substring.
I don’t know anybody who would both appreciate the fax number of the beast joke and not turn it into a conversation about 617 being the real fax number of the beast according to most manuscripts.

Yeah, but using 616 is problematic because it ruins the Barney is the antichrist bit [1], and we wouldn't want to associate NANPA area code 616 with both the beast and Grand Rapids, MI (historically, 616 covered more of western MI)
The article says "Spring 2015" but in fact the magazine was published December 29, 2015. In the text it mentions https://oeis.org/history?seq=A250001 so the interview could not have been earlier than October 2015; Wu's sequence is "recent".
There's a few sequences that jump out, this one, and the prime palindromes of 0's and 1s whose squares are palindromes; but that was August and seems too early.

667 - “fax number of the beast” - that was funny ;)
The thing about mathematics is that it can tickle your brain - in a creative way.
It's becoming increasingly difficult these days, with so many things competing for your attention and "brain-deadening" you. It was a wonderful thing to be bored and play around with math. My favorite moments were the epiphany - that there is some hidden connection between math areas or something got new meaning.

I had a similar epiphany in college, somewhere amongst Calc I, II, III, DiffEq, physics, and engineering. I kept meaning to pursue it, but life got in the way and I never did. Unfortunately, I can no longer remember what that epiphany was, and I am sad.

I can't tell which of Chai Wah Wu's submissions the interviewer was referring to. https://oeis.org/search?q=Chai%20Wah%20Wu&fmt=short&sort=cre...
You can shorten the candidates list quite a bit: https://oeis.org/search?q=author%3A%22Chai+Wah+Wu%22+2015+Pr...
