Practical reasons to save:
a) What if it isn't? i) Maybe ASI takes a lot longer or the notion of exponential intelligence gains actually doesn't happen ii) Perhaps we wipe ourselves out via climate change/nuclear war/etc (in which case money still won't matter much)
b) Money might still matter in a post-scarcity economy i) Some resources will still be scarce - how do we allocate them?
c) Saving money is wise regardless of what happens i) People still saved during the cold war when nuclear war destruction seemed imminent
Arguments for lavish living a) A post ASI world would likely look radically different. Hopefully in a good way, but still different. Might as well experience the world as it is now. i) If life becomes much worse, then either we will be dead, which means money doesn't matter, or life is terrible, in which case we might wish we'd enjoyed the good years we had. ii) If life becomes much better, then our savings probably don't matter so much as we've figured out the scarcity problem.
b) Climate change might (and already has) result in the radical transformation of ecosystems, causing many experiences to possibly not exist in the future. i) Ideally ASI would help resolve climate change? Or at least greatly mitigate it.
I, myself, am a pretty frugal person. I pay debts as quickly as I can, save as much as I can for retirement, and spend as little as possible. I think ultimately my 401k savings might useless by the time I'm old, but I do it anyways. My actions certainly conflict with the premise of my question.
I have no clue if I should even believe in the concept of the singularity. Perhaps, in a lot of ways, it is like a religion. We've replaced the second coming of Christ with the arrival of AI.
I think, ultimately, the sanest take is to assume nothing and continue to be frugal even if it's just giving myself the illusion of control over my own life into the future.
Just live your life as you see fit. Predicting the future is nigh on impossible anyway and certainly for the big life changing events. The only thing you can be certain of is that resources are getting scarcer and wealth is getting more concentrated by the few rich individuals and multinationals that are doing that already.
Live and worry not for what may be.
Is not an unreasonable question, but you can only plan for the future you know. Regardless of when AGI appears, or singularity occurs, the road you’re on right now is aging the associated costs of that. Plan for that.
With that you can spend all you earn, you will be forced to save a bit naturally due to mortgage repayments and the retirement setup and you have diverse investments.
Once you gave equity you can borrow to invest more.
If you get any bonusy kind of money like RSU then invest that as you go along unless you need it to create more cushion for your mortgage.
I used to take those things seriously in my youth. Back then we were heading rapidly into an ice age.
Don't go nuts spending your money, plan carefully for retirement, and if you're lucky, you'll get to spend those savings. But don't be so tight with it that you miss out on everything.

In the 1970s and 1980s, it was communism and nuclear war that were going to end the world. We were near certaint on those eventualities. In the 1990s, it was environmental disaster. In 2020 and 2021, it was the pandemic. And now it seems back to environmental disaster again -- I can't even keep up with the oft-parroted line that humans will extinct themselves by 2100. It could happen, who knows, but probably will not.
All the of the above worries are legitimate challenges we should be concerned about. We will have countless challenges and black swan events. The problem with these predictions is that humans (well, sapiens, anyway) always seem to find a way to survive through them.
Does it mean we won't extinct ourselves? No. But, through the past tens of thousands of years, the odds have been in our favor.
And screaming that the sky is falling only serves to work against the cause, leaving your opponents and those on the fence untrusting and unconvinced when the prediction fails to arrive as described, at the allotted time.
Maybe money will be useless.
But maybe money will still be useful.
We can’t know until it hits. Maybe not even then.
Plus there is the problem that we don’t know which century it will arrive in, if ever.
