Ah, makes sense. I had seen the mention that the KataOS implementation is running on 64-bit ARM now in QEMU, which sounded more like Fuschia's space.

Though those small devices are getting pretty big hardware these days, since it's cheap now. Some of the Nest thermostats have 512MB of RAM, and 2GB in the higher end Home hubs.

It's kinda nutty to me that my thermostat has more RAM than my Windows XP laptop did 20 years ago.

Based on the function it serves I'm actually kind of appalled. It's a thermostat. You set the temperature and a schedule and it follows along. An ESP32 can do all the Wifi and Bluetooth connectivity you want with half a megabyte of RAM. Maybe you need a few megabytes for a framebuffer for the screen it has. But half a gigabyte?!

Yeah a lot more goes into the Device than what you would expect. It's not some RTOS base hack-a-day kind of product.

Well if your thermostat or meeting room door sign runs an instance of chromium in kiosk mode to use HTML/CSS/JS for its UI then you need 2 gigabytes of RAM.
