My point was that you don't need "thousands and thousands of people with the expertise to actually proove that the algorithms used today are really safe".
If the demand existed, there would be a lot more of those people.
Again, parent poster didn't say there was a need for thousands. They were asking how many there is a demand for. One? Ten? Hundred? That's the question that is being asked.
