I've written my BSc thesis on Kubernetes bandwidth management with eBPF a year ago. This is exactly what I felt trying to research this technology. Countless blog posts about how great eBPF is, close to none useful resources... And from what I've seen since, it's only gotten marginally better.
I'm completely deaf and I can only recommend transcripts. Both zoom and teams have built-in transcription systems (though you have to enable them) and there is also an Android app called Google live transcribe. The former two work the best since everyone has a mic to their mouth and their voice never mix before going through the transcription system.
