Since the X-gene came from Celestial tinkering with humanity back when cro magnons were still a thing, the fact that there are still 'pure' strain humans without the potential for mutation around is kinda impressive.
And many, many comics have utterly ignored this idea, that *some* people can't get powers, as stuff like Spider-Island has assumed that *anyone* can get Spider-powers, or Diablo once turned an entire town into Hulks, nobody has ever 'failed and died' when exposed to cosmic rays (we never here about the fifth person who went up with Reed, Sue, Johnny and Ben, or the Red Ghost's failed assistant, or the one's who didn't become U-Foes, or all the people that didn't get Wonder Man powers from but turned into smoking ashes when Baron Zemo tried to use ionic energy on them or whatever in an attempt to empower them).
(A great source of origin stories for new characters, by the way. Who were all the *other* people experimented on in the prison where Luke Cage got his powers? And were some *less* successful, perhaps disfigured or turned into monsters? Perhaps augmented differently, where Cage got steel-hard skin, another got bones that could soften and allow him to deform his body and slip into anywhere, and another got silvery-nerves that allow him to move and react lightning-fast.)
And there's still a ton of *other* options for super-powers out there, like magic and the supernatural, ranging from Iron Fist to Ghost Rider to Dr. Strange to Helstrom, etc.
