I've been doing embedded my whole career. ESP 32 is my retirement toy. Lots
of C, forth and ASM. I still can't write a python app.

I thought there would never be a program large enough that 1mb was needed.

That depends a lot on what sort of "stuff" you work with.
For various fun projects I use the Raspberry Pico, which is a 32 bit
microcontroller with 1/4 or 1/2 MB of RAM, which is quite a lot. But a
bunch of that work uses the PIO engines -- basically programmable state
machines that talk to the I/O pins. Those have 16 bit instructions, and a
32 word program memory. No data RAM, just a couple of registers. Quite
powerful, though. One application is the DDCMP controller I published a
while ago. I'm thinking about making it talk Ethernet in software as the
next exercise...
