I believe that the intention was to say "No ability to save progress _between sessions_" in the original program, whereas the C++ implementation saves to text files.

Another portion of the article says more explicitly:

  Limitations:
    Maximum number of nodes: 200.
    The structure is stored only in memory (no disk saving).

I don't think so. Consider "It didn’t just attempt to guess the chosen animal but also learned from its mistakes, adding new questions and answers to its knowledge base. What’s more, it had the ability to save progress and load it during the next run.". Data persistence across trials is already implied by the first sentence, so what would the next "What's more, ..." part refer to - it mentions "saving" and "loading"? Even if we grant "saving" to mean updating the in-memory data structure, what would "loading" refer to? Also note the later "No ability to save progress" which directly contradicts "It had the ability to save progress". These sentences, both clearly referring to the original, are in direct contraction with each other and use the exact same terms. Inspection of the code shows that it clearly only saves the memory and not to disk.
