What's your favourite number of threads?

Now you're presumably thinking, "What a stupid question?". Surely, there's no one answer to this. It depends on several factors; what you're doing, where the code is running, and how many you need. However, I had never really thought about it in-depth before until someone asked me: "What is your favourite number of threads?". In this short (and hopefully fun) talk, I will take you through nearly all possible answers to this question and why they are both right and wrong on a technical and human level. Finally, I will give what I believe is the ultimate and final answer to the question: "What is the best number of threads?". There is no barrier to entry here. If you know what a thread is, then you're qualified enough to come along and have fun.
