That doesn't solve anything. Not only are the social implications for so many people becoming superhumans, and nearly immortal to boot, catastrophic, without the ability to replenish numbers naturally, you eventually hit a dead end, and once those who are left die, species is extinct.
Not to mention that powers are cool and all, but the implications for how fucked the world is if the number of powered people keeps growing are horrific.
If Ella wasn't clearly evil, her pitch for superhumans that exist now being left the fuck alone, and dismantling H.E.R.O. and other organizations that try to exploit this shit by turning people intentionally, would be one I'd back. Sadly, it's Ella, so chances are she is somehow gonna do worse than a megacorp that does eugenics and forces people to sign up to be cannon fodder at the point of a gun.
