what are your thoughts about this?
I think he's taking commonly used rules of thumb and treating them as facts in order to dispel them as myths.
For example, the carbon steel/stainless steel thing is absolutely true, but ONLY with regard to traditional firesteel and flint. If you use a piece of stainless steel and strike it with a piece of flint, it will not spark. It must be carbon steel. The problem arises because people use the term firesteel interchangeably to mean both traditional firesteel and ferrocerium rod. Certainly, you can use any hard sharp material to strike a ferro rod, I remember starting a thread on the subject 8 years ago...

The rule of 3's is not meant to give you 3 hours, 3 days and 3 weeks, it's just to remind you to sort your shelter first, then water, then food. It's not meant to suggest that in a freezing blizzard, you can sit on your backside for 2:59 before putting up shelter. It's just to prioritise, shelter, water, food. It's a good rule of thumb, though on a summer day, you can tackle it in any order you wish.
You can burn anything if you fire is hot enough, split or not, this is true, but wood found outdoors burns easier when the internal dry parts are exposed. It's not a myth, it's a fact and it's something you can use to help you get a good fire going.
The universal food test isnt supposed to be a rock solid bit of science, it's a rule of thumb that you can use to be safe (er) in a survival situation. Yes, dandelion and nettle will fail and yes some things will pass that could hurt you, it's no substitute for good plant ID, but if you are starving, it's still useful.
The point about rat tailed tangs is a good one, but it's nothing we dont already know. It's just that people choose full tang because they are stronger and give them more confidence, not because everything else is doomed to fail. You pay your money and take your choice.
I dont think this guy has blown any myths, I think he's just set them up as such, so he can make a video about knocking them down.
