Just read this story. Quite good. The ending is potentially quite troubling though.
Superman with no vulnerabilities now? Superman is not a God and absolute power is what he now has. No one and no thing can stop him. How long before his "God-like" status gets to him?
Unless, and this is not stated, his decreased power level applies to his overall invulnerability. Even though kryptonite no longer affects him perhaps, hopefully, very strong conventional weapons can now hurt him and maybe do him in.
Again, absolute power corrupts and the world would rightly fear a totally unstoppable power - no matter his claim to be there to serve and protect humanity.
