I don't know. It honestly sounds boring to live in a world where all our problems have been solved and there is nothing left to do or accomplish. Maybe we will all live in simulated realities, but that sounds kind of dystopic to me.

That sounds more like a failure of imagination than an argument that there will be no more fun or challenge or creative endeavors in the universe once the worst of our problems are solved. Do you really think that in a future where you no longer have to worry about death and taxes, and you have a superior brain which you can modify however you want, thus ending akrasia and unwanted depression among other things like having an even deeper sense of fun or an understanding of new problems we can't even fathom yet at our current development, that you will have less fun than you're having right now, today, reading HN?

What would be the point in doing anything? Anything you could build, program, or discover, could be done ten times better by an AI. It could probably even design entertainment, like movies, games, music, etc, far better than human artists.

A version of myself with vastly increased intelligence sounds interesting, but I'm not even sure it would be me. If you make enough modifications to your brain you become a completely different being. Different personality and thought process and little resemblance to who I am now. Which is disturbing to me at least. Along the thought of living inside of a computer doesn't exactly sound pleasant.

Even society itself might not exist anymore. Why would people interact with each other if there is nothing left to talk about that can't be instantly communicated? Why would people even spend time with each other if there are virtual realities to live in that are far more "fun". Spending eternity in a fantasy world sounds awful.

Yes I want to cure diseases and make everyone rich, but if you keep going, make a machine that solves every last minor problem and does everything there is to do, then there is nothing left for us.

And that's assuming that friendly AI is even possible, which I doubt it is, and I doubt will be discovered before AGI anyways. But either way the world we know will be utterly destroyed.
