Indeed. The one small comfort I take, is that many of the scrolls had already been removed before the burning. And hey, since you are committed, let's take that time machine project off the back burner, solve the problem, and go back and retrieve those lost scrolls.
It's my understanding that only a small section burned fully but was later rebuilt. The real cause of the fall was a couple hundred years of misuse and then conquest of course. By the end though there were many other libraries so at least some of the texts were saved.
Wikipedia is an encyclopedia. By definition it's not a primary source of information. Anything on Wikipedia comes should come from a trustworthy primary source. So technically there should be zero loss of knowledge if Wikipedia is lost. Just access would be harder (but still overall easier than it was for an average person to gain access to the library of Alexandria).
I don't know why people are so hung up about this. The amount of knowledge lost was very little to basically none. The express purpose of the Library of Alexandria was to COPY important works from around the known world. People would bring information from around the world to them, they would copy the work and the original would be returned. This meant that by definition for every piece of information there would be at least one copy at the time of recording. And because only important works were copied, it's likely a lot of copies existed. If the information was really pivotal, a lot of work would be based on it, so that's even more copies. Plus it wasn't the only place to do this, there were many more libraries around the ancient world that did the same thing. At the time it was burned, it had already been in decline for a while.
So for all the people going on about how our world would look like if it hadn't been lost, the answer is exactly the same. It had basically zero impact.

Holy fucking shit I don't even know where to start.
The mythos around the Library greatly exaggerates its importance, and the impacts of the fire. By the time they killed Hypatia (and this was a political struggle, not a religious one as the internet likes to pretend), it was not in its prime.
