Deep Learning and Artificial Intelligence are exciting science...fiction. The problem is with two of the four words in the aforementioned descriptions: Learning and Intelligence. Machines do not learn, nor is it possible for them to be intelligent. Computers are neither biologically organic or human, thus both Deep Learning and Artificial Intelligence are anthropomorphically-derived terms. We would do well to invent more accurate descriptions for these overworked and inaccurate descriptions.
I use open-source alternatives for virtually everything I do with PDF's, EXCEPT document conversion. There are some decent cloud alternatives for pdf-to-other-format conversions; unfortunately, there is no open-source alternative that comes close to Adobe or other Windows-only software packages (OmniPage is my current favorite paid program) when it comes to complex -- or sometimes even moderately complex -- document conversion. BTW, this discussion, like many others, seems to assume that Adobe is the only viable commercial pdf package; not so, IMO, there are other packages that are just as good, if not better. Why not make this discussion about paid vs. unpaid, not OpenSource versus Adobe?
