Some orders of magnitude more cost effective than a custom-fabbed chip.
Depends on what you consider profit, and particularly the number of units you decide to amortize the development costs over. How many dollars and man-hours of time went into developing that product? How units many have been sold to date? Yes, these are rhetorical questions; I don't expect answers. But you can't just say: Oh, Evolv is making outrageous profits because the cost of the materials in a DNA-20 is only $10 (or whavever it really is) and they're selling 'em for $50.
