All we did for Gaia-X was the paperwork to get the money. It had zero impact on anything we actually did. Somebody I know who knew what other firms receiving Gaia-X funds did told me the others did even less than us. We certainly did not take it very seriously, apart from it being a great source of free money, and I say that as someone who reported quite a few developer hours for Gaia-X.
I think at most this project is about sending some money to some European firms, with little regard for actual outcomes, kind of as a concealed subsidy. I'm not sure if those who started the project actually wanted that outcome in the first place? A lot of these things are just ways to use the current system to achieve goals that the system does not directly allow. It could just be incompetence, but it could also be the case that somebody knows exactly what they created with Gaia-X and is perfectly okay with the outcome.
