To add on to the video transcript that @jet@hackertalks.com posted, here is Jonah’s post from the Privacy Guides forum that more or less summarizes the video: https://discuss.privacyguides.net/t/clarify-tors-weaknesses-with-respect-to-observability/3676/14
It also includes links to useful resources and noteworthy articles referenced in the video, like the case regarding the deanonymized Tor user and the Harvard network admins. You can also toggle dark mode on the forum website, which is useful for those using anti-fingerprinting browsers such as Tor Browser or Mullvad Browser.
