Rest assured he doesn't know what he is talking about. Boiling is not cavitation. Cavitation is the sudden formation and violent supersonic collapse of vapor bubbles following quick swings in pressure such as one encounters in the water flowing from pressure to suction side of a propeller or impeller in water. It can also be cause by tortuous bends in pipes, etc, anywhere a volatile liquid flows through wild pressure gradients.
Cavitation is effect, which happens when liquid boiling and vaporize. Cavitation damage large bearings and turbines. Cavitation damage even huge turbines and bearings, which made from the metal. So, what will happen with PCB Boards after 1 year using?
Need proofs? Okay

Here's a quote from wikipedia:
The physical process of cavitation inception is similar to boiling. The major difference between the two is the thermodynamic paths that precede the formation of the vapor. Boiling occurs when the local vapor pressure of the liquid rises above its local ambient pressure and sufficient energy is present to cause the phase change to a gas. Cavitation inception occurs when the local pressure falls sufficiently far below the saturated vapor pressure, a value given by the tensile strength of the liquid at a certain temperature.
this guy on the picture just playing on public.
You mean this guy, 3M, IBM, Intel, Allied control, Coolermaster, Zotac, etc..
For instance, if we pour some 3M liquid on the table - it vaporize out less than 1 minute.
If system suddenly get leak and 250-300 liters will vaporize , how can service staff fix this problem without respirator?
That is simply not true.
Have you ever spilled liters of water in a room and seen it evaporate within minutes? Although heat of vaporization is much lower than water, it still takes a lot of energy to vaporize.
With some simple safety controls there should be no problem with toxicity.
Again, if the people at allied control/3m are living in this stuff, it can't be so harmful.
