Not where it isn't strictly necessary and I believe it is a good thing but I've seen english being used whenever people from multiple european countries are working with each other.

It is the case in IT and definitely the case in research too. Even 27 years ago when I was an intern in France, my office was next to the office of some mathematicians, I believe one japanese, a russian and another one I don't remember and they were all speaking in english.

There are plenty of European countries that do use English as the working language for technical fields, if there is not enough domestic talent.

What you say about the US research ecosystem may have been true until January 2025 but it is unfortuantely no longer the case. At the same time, the EU is finally getting its act together in both defense AND research funding. So I would forecast a sunnier future in Europe for scientists than the the US, at least for the next generation.

Care to elaborate? Last time I was in the US my prime order took over a week to be delivered because it had to get shipped from a warehouse in rural Ohio to San Diego. Here in Germany you get absolutely everything next day because the country is about the size of an average US state.

The language fragmentation certainly is an issue in the general workplace. But academia does use English as its lingua franca throughout most of the EU, though it might depend on the country. Certainly in places I've worked in academia - and yes, that has been in multiple countries in the EU - I've never had to utter a single word in something other than English in the workplace. But it is International English alright, which may be somewhat of a novelty to the native English speaker if they haven't been exposed.

> Even Amazon orders

That's wholly Amazon's problem. If I order something from BOL or Coolblue it arrives within 12-24 hours. Even small pop-and-mom webstores usually deliver within 1-2 business days. It's only Amazon that somehow manages to average more than a week (my last order at Amazon only arrived after 2 months. Guess why I no longer use their service).

I have the same trajectory as you -- multiple countries in the EU, working in academia -- but different experiences for sure. Or at least a mixed bag.

Let me list them in order of how much English sufficed:

1. The Netherlands -- common knowledge is that their English is top notch and anecdotally it was the case as well, I also got by purely with English.

2. Germany -- their English is also good but I needed German in edge cases. One edge case was finding an apartment (not speaking German simply pushed you down the list of candidates, even with a full time job in academia). Another one were university rules and announcements; not every email was in English, but arguably easy to get by with modern translation tools.

3. Czechia & Poland -- English is good among the professors but the percentage of locals at the university level is so high that most internal meetings, announcements, local seminars take place in the local language. In my experience, non-faculty university staff (department secretaries, payroll, entrance security) usually strongly dislike speaking English or outright do not speak it at all.

I've omitted some more cases where local languages are required. If you live in a country, you will eventually interact with the healthcare sector, where the language experience will likely mimic the experience at the workplace (for the countries above, it would be in the same order for the healthcare sector).

Another case is government bureaucracy. For most of the EU countries I've been to, the official language of the country is their local language and only their local language. This means that government employees are not required to speak any other language other than the official one to you, plus you might be required to fill in forms and communicate in the official language if you want to talk to them.

In my experience, the helpful/good ones may try to communicate with you in English but if you need something from them or if the bureaucrat had a bad day, you better start talking in the official language.

This is true, and something I have indeed experienced. However, this is likely true for _any_ country where English is not the official language, not just those in the EU. Besides, understanding bureaucratic lingo is not just a matter of pure linguistics. Governmental concepts rarely translate 1:1 to another nation, even those with the same official language. If you migrate to another country, part and parcel of the experience is that you _must_ contend with bureaucratic principles, rules and institutes with which you are not familiar. There is no escaping that.

That said, at least here in the Netherlands, there is certainly a movement to provide more and more governmental information in English as well. I'm not going to dox myself, but for example my muni's English website looks nigh-identical to the Dutch one.

Indeed: German is the most common first language of the EU, and French is the second-most common first language of the EU. [1] Let's from now on decide that all EU citizens have to speak one of these two languages. Language fragmentation problem solved. :-)

Or are you one of the nerds who lobbies for the idea that everybody should speak Esperanto.

Concerning the idea that "everybody in the EU should speak English": since UK left the EU, there exists no EU country anymore in which English is the only official language: only in Ireland and Malta, English is one of the official languages.
