Amazing presentation. Really enjoyed it.

[andreypanin]

The animation is awesome, but the overall impression of the presentation is that it's a bit shallow. For example, aren't networking calls system calls? They are. How does a `g` gets unblocked after a syscall? By itself or with a help from the scheduler? Also, you said shrinking of a stack is easy, but if we borrowed a continuous region of memory from the heap, we can't simply ask the OS to reduce its size to match the new stack, can we?

This was a fantastic video, thank you!

Hi, why does Goroutine needs an OS thread to run on?
Can it run without OS thread?
Thank you.
