On savings, there are two things going on. We’re drawing down our
regular post-tax savings to donate more (-$72k) but we’re still
putting money into retirement accounts (+$51k). It nets to -$20k,
though mixing pre- and post-tax numbers into one sum isn’t really
correct.
We’ve been prioritizing donations for a long
time, but it feels very different now because of the AI boom.
Some of this is that people who’ve made money in the boom will
likely be giving more soon, and so money spent now can help set up
organizations to spend future money more effectively. But more
importantly, this is a key window of opportunity: transformative AI is
coming very
quickly, for better or worse.
We want to push hard for “better”.
If you compare to previous years (2024, 2022, 2020, 2018, 2016, 2014), we’re donating a lot less than
we used to in absolute terms:

Until mid-2022 I was working at a big tech company, optimizing
to maximize donations, and now I’m at a non-profit. This means we’re
giving a larger fraction, but of a smaller amount:
Even though we’re drawing down our savings to donate, our net worth
rose 18% over the last year (adjusted for inflation). This was driven
by stock returns on our retirement savings:
Now, retirement savings growing via stock returns is how it’s
“supposed” to work: if we give away all the gains then we’ll have much
less at retirement. But I see ~three futures as AI becomes rapidly
more capable:
Things go very poorly, long-term savings are mostly useless,
and we really wish we’d done more.
Things go very well, the world is very wealthy, we don’t need
the additional money.
Somehow, AI ends up being not that big a deal, and the world is
still pretty normal financially.
It’s really only in that last
world where our savings translate into us having a better life,
and as AI continues not hitting a wall I see the chances of ending up
in a basically normal world getting pretty small. While we shouldn’t
donate to where we’d be destitute if we’re wrong, we’re not in danger
of that. [1] So I think we should continue to draw down our
non-retirement savings to donate more during this critical period.
Writing this post also got me thinking about our retirement
contributions. We’re both contriubuting the maximum, which I think often
makes sense even if you don’t expect a normal retirement, from a
perspective of protecting savings. Since we’re in a good enough
position financially and donating seems very urgent, I now think we
should stop contributing to have more to donate going forward.
Evaluating Predictions
Back in 2024 I made a list of what I expected to write in 2026. How
did reality differ from expectations?
2024: I think there’s a good chance we’ll have switched from
giving 50% to some form of salary
sacrifice. If we do, our pay, donations, and taxes will all be a
lot lower.
I did this for a little while. I started at
a 10% reduction, and then when Julia’s work decided to no longer
support voluntary salary reductions I went to 75%. Then a few months
ago I decided
to stop since I wanted more flexibility in targeting donations.
2024: Childcare should be similar: the nanny share is working and I
expect we’ll do something similar at least until our youngest starts
kindergarten in Fall 2026 (and will show up in the 2028 update).
Yup, still doing a nanny share with our former housemate. While there
was a bit where our nanny left and it took us a few tries to find
someone who worked out, this is now going well again. We haven’t
decided what we’ll do for afterschool when our youngest starts school
in the Fall.
2024: I’d like to hope I have a better way of accounting for housing
and savings in general and have gone back and redone all my previous
numbers under the new system, but since that sounds like a ton of work
I doubt I’ll have done that.
My prediction that I would be lazy was correct. This post represents
zero accounting improvements, only more data due to the passage of
time.
2024: I put about a 10% chance on AI, war, or other major events in this
timeframe changing things enough that everything is weird in hard to
predict ways.
The world is appreciably different from two years ago, but not in ways
that strongly impacted our spending.
Making New Predictions
Let’s try and make some similar predictions for 2028:
My odds that the world has changed substantially are up
significantly, maybe 55%, primarily due to AI. I’d put about 10% on
futures where things go very badly, where I’m not here to write a
followup and you’re not here to read one. Then maybe 10% on really
good futures where there’s no need for me to work on biosecurity and I
can do music, dance, and blogging full time. And 35% on weird futures
where we’re not dead but it’s not clearly good either. Don’t put a
lot of weight on these numbers!
Childcare costs will be down a lot, because all three kids will
be in school. But we’ll still need to pay for afterschool, holidays,
and vacations. Our oldest will be in 8th grade, so no college costs
yet. Back in
2018 I was thinking that sometime around 2028 I might be moving
from earning to give to direct work (due to the effective 100%
marginal tax rate), but I ended up doing this earlier and for
non-college reasons.
We won’t be pulling from savings to fund donations because
we’ll have finished giving away our remaining non-retirement savings.
But with so much lower childcare costs we’ll probably still be able to
give over 50%.
We don’t have any expensive house projects. With how much the
world could change soon I want to keep options
open, and not lock up money in the house.
We’re still living in the same house, and our housing costs
will have gone down slightly because rents will have gone up a
little (in a combination of real and nominal terms) but our
mortgage is fixed-rate.
Our shared car
is a 2013 Honda Fit, and while these are great cars there’s a decent
chance it won’t last much longer. Might need to make a substantial
payment here.
Details
I’ve used the same approach as
last
year, which was unchanged from
2022 and very
similar before then. Numbers below are monthly, based on 2025
spending.
Donations: $11.9k (81% of 2025
adjusted gross income)
Taxes: $3.0k
Income tax: $500
State tax: $500
Social Security tax: $900
Medicare tax: $200
Property tax: $800
Childcare: $3.6k ($150/workday, three kids)
Housing: $2.0k
Note: this is tricky; see details below on how this is calculated
One time expenses (all time)
Purchase and all one-time expenses up through the 2024 update: $1.1M
Major one-time expenses since the 2024 update: $31.8k:
Ongoing expenses, covering the whole house including the tenants’ unit:
Electricity: $92
Gas (Heat): $257
Water/Sewer: $179
Other: $83
Rent income: $4.8k
Retirement saving: $4.3k (all pre-tax)
Other savings: -$6.4k (see below)
Medical: $218 in pre-tax health insurance, ~$400 in post-tax
co-pays etc
Food: $964 (two adults, and three kids 11y, 9y, 4y)
Other: $1k
Includes phone bills, taxis, car rentals, clothes, vacation,
stuff for the kids, and other smaller expenses.
Because we are no longer tracking our expenses to the
dollar, the distinction between “Other” and “Savings” is an
estimate.
[1] Our house is 2⁄3 paid off, if we used savings to finish it off
that would leave ~$1M saved. At a 4%
safe withdrawal income this would be $3.3k/month. We also rent
out several parts of our house, totalling $4.8k/month, which brings us
to ~$100k/y of raw income. This would need to cover taxes, health
insurance, utilities, house maintenance, food, etc, but almost
everyone lives on far less. I think the largest risk is that we get a
non-extinction future that’s still quite bad, but I have trouble
seeing moderately higher savings making a large difference there.
Donating 80% While It Still Counts
Link post
Julia and I had been giving half since 2014, but in 2025 we drew on our savings to donate 81%. It looks to us like we’re in a critical window for keeping the introduction of very powerful AI systems from being disastrous, and we want to do what we can while we still can.
Here’s what that looks like in the context of our overall spending:

I feel good about this change. I’m now building an early warning system for engineered pandemics, which is urgent and important as AI increasingly substitutes for advice from expert virologists. It does mean donating much less than I would have if I’d continued in big tech, but I think this was well worth it. While money can enable important work, I see a lot of projects that primarily need dedicated people to bring them into existence, and I’d be excited for others to switch to direct work.
Even though we’re drawing down our savings to donate, our net worth rose 18% over the last year (adjusted for inflation). This was driven by stock returns on our retirement savings:
