One of my most favorite museums in the world used to be the Science Museum in London, then I visited it and discovered the steam engine in the entrance doesn't run, the ship model gallery has been sent to storage never to be seen again to be replaced with a gift shop, I couldn't find the working Babbage engine section, in fact basically every display I wanted to see was gone and replaced by junk.
These so called "modernized" displays are nothing better than what you could read online, I want to go to a museum to see *actual* history, not to see a cartoon representation of a simplified version of history that assumes I am a moron.
I think the curators of science/technology museums need to view themselves in the same way as curators of art museums do, their purpose is to display the "art" not to tell me about the art with pretty cartoons after they ship the art to the storage warehouse.
