> We have so many more people using computer devices and the internet now. We have to account for them to some extent and a lot of libraries do that for us, but it does make them heavier.

A significant percentage (majority?) of those devices and internet connections are low powered and slow compared to what most readers here are using

Those heavy libraries can often exclude those users simply because they can't adequately run the fancy features those libraries provide

There's a balance here that I think we, as an industry, are not managing well
