Linkrot is a real problem. Especially for those sites that disappear before the archive can get to them. On another note, the more dynamic the web becomes the harder it will be to archive so if you think that the 1994 content is a problem wait until you live in 2040 and you want to read some pages from 2017.
For even more accuracy save a Chromium binary of the version at the time so it'll look exactly as intended.
