> the low barrier of entry and hype has resulted in a huge amount of people downloading Keras, copying a bunch of code, tuning a few parameters, and then putting their result on arXiv so they can put AI research on their resume. This has resulted in so much noise and low quality work that it really hurts the field.

Then the problem isn't the low barrier and ease of use, it's with arXiv's filtering and how resumes are valued and verified.
