You need to look 2-8 years in the future. AI is narrow now but it will not stay that way. See unsupervised learning, adversarial methods, consciousness prior, day/night cycles, and more. Imagine an AI that you can communicate with via webcam that is building as you talk to it. That's where we are headed. It's naive to think that humans will still be the ones crossing the semantic gap.

AI will create unique things, not clones. Think if you had an army of programmers that worked 1000x faster than any one team around today, all at the cost of electricity. That's where we are headed.

This is not true. I'm not sure where you are getting your information from.

You don't understand the field if you believe this. Biological thought is limited to time-serialized samples and 20-60hz response times. AI will have no such limitations. We will be able to create a program to do (sound -> code) mappings. Things like "Alexa, build me a website where people can talk to each other like reddit".

AI will replace coders too. It's just crossing the semantic gap. The best coder today is like the best chess player before deep blue.
