Thanks. I did consider the other meaning. Note that in “product development”, a product is being developed, while in “intelligence explosion”, intelligence is exploding. That doesn’t by itself make the interpretation impossible; “intelligence explosion” could instead be analogous to “product evolution”, say. But the distracting interpretation where intelligence is being exploded made the interpretation of “explosion” as a nominalization of “explode” seem even more unnatural, as did the use elsewhere of “an intelligence explosion” and “the intelligence explosion”. (Likewise, in the case of “the explosion of fireworks”, at first I read that as fireworks being exploded and not fireworks exploding, but there it doesn’t matter, because fireworks being exploded makes sense.)
