@LovingFalloutLondon1954@mastodon.social @rudy@mstdn.ca Sorry, English is not my native language, and pretty blind to the context elements which make "guy" gender neutral or not. If I understand the definition on the Wiktionary correctly, the plural is more gender neutral than the singular https://en.wiktionary.org/wiki/guy

@LovingFalloutLondon1954@mastodon.social @rudy@mstdn.ca Actually, the head of the Academie Française (not a guy by the way) said it was "la COVID" while everyone else was already saying "le COVID", 6 years later, it's still not settled, wis some people having strong opinions on the matter

https://www.lemonde.fr/idees/article/2026/05/26/etudiants-etrangers-la-france-gagne-a-ouvrir-ses-portes-elle-perdra-a-les-fermer_6693845_3232.html

«Les titres de séjour doivent être renouvelés chaque année, ce qui produit des ruptures de droits. Et lorsque les étudiants finissent par décrocher leur diplôme français, beaucoup repartent faute d’accompagnement vers l’emploi. Le problème n’a jamais été le prix. Le problème, c’est tout ce qui se passe avant et après, c’est-à-dire les démarches, l’attente, le logement, les conditions d’études, l’accès à l’emploi.

L’université française est un bien commun. Elle est ouverte parce que c’est sa tradition depuis la Sorbonne du Moyen Age. Elle est exigeante parce qu’accueillir suppose des moyens. Les étudiants internationaux rapportent 1,35 milliard d’euros par an à l’économie française, ils nourrissent la recherche (38 % des doctorants sont étrangers), ils deviennent, après leur retour, des ambassadeurs économiques et culturels. La France doit voir l’effort qui leur est consacré comme un investissement d’avenir.»

@ottaross@mastodon.social @Enthalpiste@social.sciences.re It's an excellent book, but the loss of the digital archives of the 21st century is only an element of background, not the main subject
