You definitely need to count that. Even with pretty conservative assumptions, it massively changes the outcomes. For those numbers, and assuming 5% growth of investments after inflation, you can retire in 23.5 years (using https://networthify.com/calculator/earlyretirement?income=28... for convenience).
It might be worth reminding Australians in the audience that possession of pornographic drawings or cartoons of figures deemed to be "childlike" is considered equivalent to possession of actual child pornography, in this country. As a result I suspect this kind of site and the diffusion model tech is dangerous for Australians to use until there are more deliberate guarantees against the creation of such images. Our laws will lag technology for many years, but the result here is a chilling effect whereby I'm not willing to even explore it much for fear of potential unintended consequences.
For those who've not seen this domain before (although it is showing up more frequently on HN these days), Psyche "is a digital magazine from Aeon that illuminates the human condition through psychology, philosophy and the arts."
Its essays are hit and miss for me (and there's a fair bit of miss from this one, even though I think the discussion here is interesting...), but there's more than enough interesting ones to keep me coming back. It's one of the few sites around that has convinced me to join its newsletter. And if you're in a cosmopolitan city (Melbourne, London, New York, etc) they host semi-regular philosophy night events too. Worth a look.
I have a first generation iPad from 2010 that still works. It's on iOS 4 or something. We use it permanently plugged in as a photo slideshow thingy, and play Jetpack Joyride and Peggle on it a few days a week.
I keep expecting it to just not turn on one day soon, but it's still chugging along happily. I plugged it into a laptop and updated the photos on it a few months ago, with the expectation that doing so would have a fair chance of killing it for good, but it handled that happily too and kept on truckin'.
After 12 years I think I've had pretty good value for money out of it!
You sound like a slightly older version of me. And then I read your profile and you work in precisely the same field. I honestly feel that robotics is one of the few domains in which this kind of play can yield a sustaining and continually interesting career. I'm currently building an autonomous wheelchair for about half my usual rates just because it sounded fun. :-)
One fun heuristic I've used for thought-experiments in futurology is to ask "what will be to cheap to charge for eventually, and what comes of that?" For example, electricity. Or water. Or fuel/energy for vehicles? Or computation? What would you do if you had unlimited internet bandwidth? What will have scarcity value when we can harvest asteroids for unlimited diamonds (or just... not stockpile them)?
There's the missing Step #2 problem, but it's still interesting to think through. And in my personal experience, it can also lead to you creating the future but too early for it to be truly viable. And that can 'waste' a lot of time, if you don't enjoy or value the the exploration in and of itself.
I'm interested by #3, as it is imminently to be my own situation (by choice). The few people who know thus far are all close friends, and even then aren't completely aware that "living off my savings" comes with the additional "and I'm >95% confident that I can do so in perpetuity." My parents think I'll be bored in short order, which may be true. But I've no idea how the rest of society would see it. Envious? Pleased for me? Suspicious of how it was achieved? Something else?
Just as one counter data point to your observation of your social circles: 2020 made me reconsider things. I also did the maths and concluded I was already the FI part of FIRE. I thought some more about what I wanted to do with my life, stayed several more months to give myself time to reflect on things, and then ultimately resigned with no intention to find another job. I will wrap up in two weeks time.
