Sadly, "deep learning" (much like "AI" itself) has become more of a marketing term and less of a technical term these days.

If I tell someone I made a deep learning system, it conveys no details other than it's something besides a single linear discriminator.

deep learning is in the "Peak of Inflated Expectations" phase of our never ending tech hype cycle. Like most buzzwords, it holds meaning for practitioners, but when marketing dweebs with no knowledge are hired to write endless clickbait about technical terms with no underlying understanding, it dilutes the entire vocabulary ecosystem until even the practitioners can't describe what they do using their own terminology anymore.
