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)
"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."
