I'm not saying tiny lines aren't cool. I'm just saying the idea you can't be successful if you make cruder, older resolution chips is probably wrong: Your printer and your car don't care if the Dice is 10mm not 5mm, and the track lines are 5x wider. MILSPEC stuff probably runs cruder for other reasons. Resiliency? Verilog proofs?
I also have no idea how many dice you get off a single ingot these days. 300mm wide, but how long?
