>> The more primitive something is, the easier we can master it
"The more advanced something is, the less we NEED to master it."
That's the bottom line: "why are you struggling to fit your modern algorithm into an 8bit, 16 mip, 32kbyte flash, cpu, when you could get a 32bit, 50 mip, 256kb flash CPU for about the same price?"
And the answer is "I'm not struggling; my algorithm is trivial even on the 8bit CPU, 32k is a lot of flash, and why are YOU sending a 4-layer PCB to fab for your 100pin LQFP and struggling with noise, EMI, and other issues, when you could have built a prototype on a protoboard last week?"
