It's like switching from Assembler to C or Python. You don't need to do a lot of the tedious low level stuff by hand any more, and probably the computer can do it better than you. This will make AI more accessible, not less.
General A.I. building general A.I. would be frightening, yes. That isn't what this article is about. We're still just talking about ML image classifiers here.
So only people who work with ML classifiers should be concerned? An increasing need for data scientists and ML researchers has been forecast for months and here's a technology to eliminate that need. Hope your next dream job wasn't based on ML.
But anyone who has a large number of ML developers working on tasks could have (and probably should have) done this [automate or semi-automate generation of ML networks] already. The best (i.e.,laziest) programmers automate their work as much as possible.
This situation has the feel of a "Singularity": just as Fall's incoming college students embark on an introductory class in ML, they read about how Google and others might eliminate the need to develop with ML.
