I generally agree with the thesis of the blog post.

I'd like to add that I feel frustrated when try out a screen at a museum and it not working (malfunctioning). I have been to NASA's Kennedy's Space Center (KSC) many times (like 5-6). Although they have got most of the exhibits working in good order, some of them are broken or not functioning well anymore. I still appreciate KSC (am an annual member), but I wish there is some philanthropist or the government fund to renovate these museums periodically...
