Sous vide is a fancy French word for a shockingly simple cooking method, that is, cooking with an extremely good thermostat. No more and no less.
Actually, any French speaker will tell you,
Then again all web resources will tell you that sous vide entails cooking in some form of an airtight container, and about half will tell you that the container is under vacuum, hence the french term "sous vide".[/quote]
You are correct in the French language. You are also correct that originally (historically) vacuum was considered part of the sous vide idea.
But scientifically, it is not possible to create pressure in a flexible plastic bag. Try it. Use the most powerful vacuum machine to draw a vacuum in a plastic bag. At the end if you measure the pressure, it will be the same as atmospheric pressure. You can only create vacuum (pressure) in a rigid container.
Again, neither vacuum nor pressure is needed to keep precise temperature setting.
