These translations are not perfect, yet. But good enough for my needs. Any professional translator services would in any case be beyond our budget. The advantage of using agentic coding tools here (enabled by using a site generator rather than a CMS) is that I can get systematic about dealing with jargon, SEO, and frequently used phrases. I simply document all that and instruct the tool to refer to that. The funny thing is that most of the models are pretty good at fixing their own mistakes if you just ask them too. I asked it to look for examples of "denglish" (German English) in its own German translations and then to fix it. It found a few examples and the suggested fixes were fine.
A lot of people are focusing on the negative here. I like to look at the positive. We're approaching the moment where any person on this planet will be able to communicate directly with any other person on this planet without the need for translators. The tools already exist for this. But they need a lot of work on quality.
A second point here is that the role of English as the most popular intermediary language is disappearing as well. I'm not a native speaker. When I talk to foreigners from wherever, it's mostly in (bad) English. By definition that limits me to talking to people that have had enough education and exposure to English. This is very limiting. A lot of the people we need to talk to here in Germany aren't all that comfortable speaking English.
