    Autonomous cars will need 300 gigabytes of DRAM or more

    So regular cars won’t. OK.

      It doesn’t mean that RAM won’t be there. Remember microwave ovens from 30 years ago? 2 electromechanical switches: power and timer. That’s all that is needed. And look at modern microwaves now… Interesting how much RAM they have already. 64 KiB? 8 MiB? More?

        This page from STMicroelectronics suggests a microwave microcontroller would have about 40 KB of RAM and 256 KB of flash storage.

        I am assuming this is for a relatively mainstream microwave without a bloated interface and ads.

        Although it seems there are mutiple microcontrollers for different components.

        I don’t get the thing with microwaves, at least where I live, all cheap microwaves have mechanical timers, electronic microwaves are a premium product and cost more.

          It seems like I saw a couple bottom end underpowered microwaves that are still mechanical, but most here are electronic. Certainly any with useful power (1100-1200w@120v) are electronic. Anything larger that on a single plate are electronic. I don’t know idpf that means I’m looking at premium products, but almost all here are.

          So I have all these buttons I almost never use, all these useless programs. I have to admit the “auto-defrost” program on my current one works really well, but aside from that, I mostly use “+30s”

            I find that 700w is enough, I can do anything on it from heating tea to making pizzas and lasagnas.

            All microwave food packages says to heat at 700w anyway.

              Huh. Here I believe food packages tend to assume 1100w, so anything lower is slow
