Google Reader was such a great webapp. This and Google Listen are the two Google apps I miss the most.

To be honest: I don't think that's much of a problem (unless...). The pathogens on earth are all adapted to attack (if you want to use this verb on a cellular level) us and others on earth. They would most likely not pose a threat to any other lifeforms that have evolved on other planets, unless our way of evolution is the only one which is able to produce life. And that is a big unless, because apart from the panspermia theory (life came to us with a meteor) there is no reason to assume that life has to work the same way it does for us.
I don't think so. Of course it's hard to predict what Europe will look like in 100 years, but I'd like to image the EU more as a service provider for its member states. Maybe the military will be combined and the economy is already very much linked together which will increase. But I don't think the member states will cease to exist as sovereign nations. Europe is far more diverse not only in language but also in culture. That is in my opinion a strong feature of the union as it is a union in diversity.
Just because the source code is available it does not mean it is free to use and do with it what you want. The license explicitly states that you may use it but have to publish it for free and follow the Steam subscriber agreement. Also this is just source code, not the assets (at least as far as I understand it).
Paperless-AI is fantastic. I had 750 untagged documents (all my physical mail since 2017). Paperless-AI processed all of them using a local Ollama installation, tagged them, created correspondants and a title for each document. So much work I didn't have to do... 😍
