Coding Ethics or Ethics Coding

Consider these two headlines:

With The Rise Of Legal Weed, Drug Education Moves From 'Don't' to 'Delay'

 

Should Self-Driving Cars Have Ethics?

The interesting thing with the former headline is that codification influences the ethics around the drug/weed/chemical.

With the latter headline the reverse seems to be the idea, we have the ethics, we just need to do the coding.
