Using curved, matching quotation marks is typographic design and style, as is using hyphens, en, and em dashes correctly in context. Many tools will automatically use the correct typographic symbols in context in the same way they’ll automatically insert periods and spaces in response to double-spacing. And even setting that aside—typographic style is a long-standing craft of design. Why would we want to let LLMs take that away from us?
Quotes like that were an issue long before AI. Classically, it was a sign that something was copied from Word or Outlook. I used to run into it constantly 15 years ago, I had a co-worker run into it a couple weeks ago, no AI involved.
As much as I’ve seen this, I’ve never seen anyone get fired for it, this includes times where it broke production.
Do you really think that the LLM knows or cares whether you get fired? Your mistake here is treating LLMs are sentient when all they really are is a token probability predictor.
I think some programs on some computers will automatically use curved quotations marks (even if they can be disabled, it is not always done), and sometimes they are deliberately entered manually, so that is not necessarily the AI.
