@tibfox wow thank you for your long and thoughtful answer! I hope you can make it to the discussion on Friday, I feel that this topic could be something we could use as a DAO to start. After all we all are some museum's audience and we know what we miss and what we like!

I was a bit provocative stating that museums are oldfashioned and outdated. Not all of them are. We have a beautiful children's museum in my home town which has amazing, prize winning exhibitions for children up to 10 years. But after that the field becomes quite scarce. Although I believe it would be so easy! There is so much knowledge in the collections of museums, so many stories to be told. However, I believe that tech, nature and science have a better standing in engaging young people and audiences in general.
It becomes trickier when museums cover art - historical art, contemporary art, national art, applied art, they have a harder time "selling" their exhibits to the audience.
There are of course exemptions to the rule, pity I didn't make it to Kunsthalle Hamburg, time was too short.

I always wonder why museums do not exhibit more art of unknown and contemporary artists.

What I learned from working with MAK there are many donors to please, who make the most powerful group within stakeholders, although they represent a minority. Also, museums in Austria at least have a clear positioning or mission. Galleries feature young, unknown artists, and if they reach a certain recognition (= value of works measured in cash) they might be invited to contribute to a museum's exhibition. The MAK only purchases pieces that have been produced for one of their exhibitions by an artist, they do not commission works. And they only collect what is recognized (see above). A curator might fiercely contradict the "recognition" part as they are part of the recognition system. Still, they have expertise, only they seldom share it but own it.
Another aspect is that museums are funded by either foundations usually based on private collections or they are funded by the state. In Austria the state is like a VC. My capital, my rules.
But there are other models and I think we should also discuss how a DAO could be structured to create and own something equivalent to a museum. After all a museum is just an extensive collection with a purpose.

In my view museums work a bit like politics: everyone knows that there has to be change within the system, everyone talks about it but in the end everyone agrees to stick to business as usual.
I believe we as a DAO can break through these restrictions and system boundaries, as we are not bound by them. And in creating something new, we could address the established institutions. Just like the MAK.
