Yes, I agree with what you’re saying, @jamesnorton. I found those articles to be interesting nonetheless, despite the limited practical utility of the proposed approach.
I don’t see many blog posts and articles about using Elixir for machine learning and deep learning in particular, likely due to the limitations you mentioned. I’m easily excited.
I welcome any writings on the subject, if only as food for thought 
As you can see in my post above from a couple of days ago, I share your concerns about the computational aspects of machine learning in pure Elixir, accessing GPUs via CUDA, etc.
Personally, I’m more hopeful about the possibilities of using Elixir for the non-computational and operational aspects of data science, such as data gathering and wrangling, model serving/exposure, model distribution for federated/collaborative learning, monitoring model behaviour, etc.
