sadly, there are a lot of important newer x86 patents that are still years off, and new ones are added every few years, so the best you could do next year is a 20 year old chip.

Basic x86_64 in hardware and software emulation of extensions is a more viable path than full x86 emulation on ARM. What we don't know if anybody is working on independent x86_64 CPUs.
Yeah it's never really an issue for me. I just make sure to bring my charger with me if I'm out somewhere with my laptop. Most computing is done on my desktop though, I don't use a laptop very much
Also, most laptops aren't at the 100Wh battery ceiling --- in 2025, it's exasperatingly difficult to find a non-gaming laptop that has a 100 (or 99) Wh battery.
You can use a USB powerstation with USB PD. The computer won't know about its remaining charge on any powerstation that I'm aware of, but that'll let you functionally untether for as long as you want, as long as you're willing to carry the powerstation, plug it in when the internal battery gets low, and remember to charge it.
I keep a small 100Wh USB powerstation in my backpack, and a larger powerstation in the car.
This is considerably larger (and comes with a lot more electronics), but also ten times that amount of juice. powertop says that my laptop is currently drawing 10.6 watts as I'm sitting here. That thing could run my laptop at the current power usage for 4.2 days, assuming no idle screen powerdown or anything like that.
Today, though, Linux doesn't have the ability to have a USB power station and treat it as another BAT /sys/class/power_supply device, and there aren't USB PD power stations that report their charge out there that I'm aware of. If you have a laptop running on USB PD power, it simply acts as if it's connected to an infinite source of AC wall power.
