Wenn sie das wollen, sollte es angesichts der aktuellen Entwicklung von KI-Übersetzungswerkzeugen ziemlich einfach sein.

For comparison, it looks like Metaculus added Czech language interface ahead of a large tournament about a year and a half ago. They had about 40k total users at that time, and Manifold is approaching or has met that number. However, since Manifold targets a wider demographic and is still making large interface changes, I suspect the perceived cost of internationalization will make it less likely than not by 2025.

I am not translating this for you, in order to highlight the necessity of such efforts.
