kai_mac··on Ask HN: Are people optimistic about the future?
The remaining carbon budget for limiting warming to 2°C with 66% probability was estimated (in 2022) as equivalent to 23 years of (then) current CO2 emissions. It does not seem likely that we will be anywhere near zero CO2 emissions in 19 years. We are heading towards a hothouse Earth without the technology to reverse this on any meaningful scale. So no I don't think humans will be more happy, I think they will be hotter, more underwater and more hungry.

Side note: nobody else seems to have mentioned climate change yet in this thread. The fact that we are currently in the process of determining, through our CO2 emissions, what the medium to long term future of human society looks like seems...incredibly significant! And yet people don't seem to want to talk about it. Is it ignorance? Or resignation?

kai_mac··on Gemini, Gophers, and Fingers. Oh My Alternative Internets Beyond HTTPS
I do think it's a shame that Gemini doesn't have images and richer text, but maybe it would be even less popular/successful if it had those. Gemini won't be the last of these simple protocols so it's a useful learning opportunity.

My project at the moment is kind of related to these "simple web" ideas. Instead of giving up on HTML altogether I'm making a simple web browser, to see if there's a way to render even relatively complex existing pages, like Wikipedia or news sites, without needing to implement much or any CSS. A bit like "reader mode". (link if you are interested: https://codeberg.org/kaimac/weaver)

kai_mac··on Assessing the size and uncertainty of remaining carbon budgets (2023)
"For limiting warming to 2°C with 66% or 90% probability, the RCBs are estimated at 940 and 500 GtCO2, respectively. With 40 GtCO2 emitted in 2022, this is roughly equivalent to 23 and 12 years of current CO2 emissions for a 66% or 90% chance, respectively, of limiting warming to 2 °C and 6 years of emissions for a 50% chance of 1.5 °C."
kai_mac··on Is anybody else bored of talking about AI?
The 4% figure is for data centres generally afaik, and it's pre-AI

Of course nearly all of that growth is going to be AI
