Can you please use the rule of two-thirds next time for showing yourself on the left and content on right? UX-wise, it is very difficult to interpret. The text on the right is just next to you, without a good distance. Moving to the next video. Thanks for the video, though. Content seems useful as for the first 2 mins I saw. Other graphics are super amazing as well. :-)

Very interesting, thanks!
Just one thing. For next time, when you make a video, can you explicitly add the version numbers? Whereas it would have worked fine 4 months ago, there have been breaking changes now. (I'm glad you added a link to the source code, where I could find the dependency discrepancies :-))

In the example, tracing.js does not work, it gets an error on line 9, -Cannot read property -ERROR- of undefined.- The problem seems to be that -opentelemetry/core does not export LogLevel. When I comment out LogLevel it runs, but it does not send any telemetry. I verified this by using ConsoleSpanExporter.
