TDD is dead?, Mock alternatives [on hold]

This video of: TDD is dead? https://youtu.be/z9quxZsLcfo, give me more reasons to go away from Mock objects... I think TDD is not dead, but Mocking could be?. Most of the time it is tedious, and very hard to maintain... Instead of mock, what else can we use? I know this is a technology independent matter, but if you could refer to C# example or library will be great.
