Note that a similar idea had already been suggested by Shen et al. (2025) in Speculative Decoding via Hybrid Drafting and Rollback-Aware Branch Parallelism (https://arxiv.org/abs/2506.01979), but with lower performance.
I'm not sure what you'd call a "pioneering scientific advancement", but there is an increasing amount of examples showing that LLMs can be used for research (with agents, particularly). A survey about this was published a few months ago: https://aclanthology.org/2025.emnlp-main.895.pdf
What we also learned after GPT-3.5 is that, to circumvent the need for new training data, we could simply resort to existing LLMs to generate new, synthetic data. I would not be surprised if the em dash is the product of synthetically generated data (perhaps forced to be present in this data) used for the training of newer models.
To add on what's been said already on slide decks, another great slide creation package in Typst is touying[1]. I've used it to create my own academic theme[2] for courses or conference presentations.
There is no inherent need for humans to be "trained". Children can solve problems on their own given a comprehensible context (e.g., puzzles). Knowledge does not necessarily come from direct training by other humans, but can also be obtained through contextual cues and general world knowledge.
For the AI to say this or to produce the correct answer would be easily achievable with post-training. That's what was done for the strawberry problem. But it's just telling the model what to reply/what tools to use in that exact situation. There's nothing about "self-awareness".
What's the issue with "… disproportionately affects …"? It seems to be a correct English construction (even though the frequency in COCA is relatively low; 72).
Some examples:
> Indeed, the recent cases of hyperinflation in Brazil, Argentina, and Poland illustrate that although hyperinflation is harmful to savers and disproportionately affects the poor (The Independent Review)
> A hearing is set Thursday on the new version of a legislative bill to eliminate scheduled pay increases for state employees that nixes a section that disproportionately affects rural legislative information offices (USA Today)
> Suicide is a key mental health issue which disproportionately affects men. (london.gov.uk)
FYI, the only English article at the time of posting was Entrevue's, which is why it was initially chosen. But indeed, Le Monde's article is much better.
