It would be a shame for the museum to deal exclusively with the internet. I'd rather see that as a part of a broader museum covering the many areas in which Bell Labs did important work.
I wonder how much would have to be done to make it safe for museum or educational use. Some of the Murray Hill buildings have, or had when I was there, not only natural gas lines but hydrogen lines in the walls. Some labs used very nasty chemicals, such as hydrofluoric acid.
Two things I think are frequently lost in these discussions:
1. When Fauci made his statement about people not needing to wear masks, people tend to forget the context of the situation. At the time, mask manufacturers were caught off-guard and there was a huge run on masks. They were extremely hard to find to buy. Hospitals were running out and having a very hard time procuring the masks that they needed to perform operations. They were actively trying to discourage people from hoarding masks so that medical providers could have "dibs" on acquiring them first.
Once the supply line caught up with demand and they were more easily obtainable, they changed their position—but not because the facts or evidence of their effectiveness changed.
It wasn't just masks to which this flawed logic was applied. When the COVID vaccines first became available, people who were over the age of 65 were given priority on getting them. A bunch of people willfully ignorantly took that to mean that people who were younger just plain didn't benefit from having the vaccine. Nothing could be further from the truth; it benefits them greatly. But with a highly limited supply, we necessarily had to prioritize who got the shots first.
2. When you wear a mask, it isn't particularly effective in protecting you from COVID. Its purpose is to protect everyone else if you have COVID, especially since in the initial stage of infection many people were asymptomatic. As mentioned in comments above, it prevents a 10-foot plume of aerosolized infected saliva from projecting forth from your sneezes, coughs, and even just breathing. The idea is that if everyone is wearing a mask to protect everyone else, then you'll have a much higher level of protection also.
Living in the South of the US, I can't count the number of times I heard chuckleheads explain to me how those masks still let particles through. They couldn't wrap their brains around the point being that those particles for the most part won't be there if everyone is wearing masks. And it's not just COVID that controlled by masks. Did anyone notice that cases of the flu dropped to a fraction of its normal rate of infection where people consistently masked up?
