Idk if this counts but I only currently think I am. I know life as it exists right now is full of suffering, pain, conflict, consumption, and boredom. But I also know it's unlikely that humanity will ever voluntarily go extinct, so in the far future (long after I'm gone) I hope advancements in technology could make life worth living by exponentially increasing and decreasing the threshold for pleasure and pain a person can experience, respectively. I'd hope we'd also minimize the amount of consumption we do as a specifies and will be able to reverse any damage we've already done to the planet, along with improving the quality of life for all other living creatures on it, so our existence will be morally justified.
This is all assuming we're capable of using far-future technology to improve things, it's also possible we'll only use it to make things worse. If that turns out to be the case then I'd suggest we just focus on programing super intelligent robots that could accomplish a tangible amount of good in our stead. If we can't even do that, then yeah, we should probably just die.
