How realistic is the singularity in our lifetimes (next 50 years or so)

I'm an avid long term listener of mysterious universe podcast and I've been listening to the back catalogue and it's funny hearing things singularity related that were 5-10 years out, from episodes 10 years ago which still haven't come to fruition.

How realistic is singularity in our lifetimes ? I see the point that AI can self learn the moment everything changes overnight.

I'm hoping all kinds of diseases are cured, that's what I'm.most looking forward to. I have no interest in augmentation of myself, but I fear a world where this will be a requirement to compete with everyone else.

Do you guys really think this will happen in our lifetimes ? It would suck to just miss out on how insane advancement is going to be, potentially missing out on never dying.
