Nice videos. Could you invite him once more to do some videos on the modern C# features? As well as Vectors and intrinsics?

Great explanation. Specially the ??= operator.

Why does this video seem to imply that the null conditional makes the code thread-safe? He talks about the if statement and the cancellation not being thread-safe, but then they switch over to using the null-conditional operator without further addressing the issue of thread-safety? What... :/ It makes no sense that they gloss over that then just switch over to new syntax that doesn't address any of those concerns. I don't understand the point of bringing thread-safety into the talk without a corresponding resolve.

Explicit code always wins over compressed and hard to ready code any day. The developers for C# should focus more on useful additions to the language instead of inventing 10 more ways of doing the exact same thing in harder to read ways.
