> You can't make blanket claims that apply to all of humanity
Except Soylent are doing exactly that.
That's called marketing. When a business does it, you take it with a grain of salt. When an individual says something like this, you have to take it a little more seriously otherwise you're not giving the person their due.
But I do appreciate your point and you did make me scratch my head when I first read it.
To you. It's your opinion, not mine. You could say "The FDA would strongly condemn something like this" or "I think this is unsafe" but you can't say it is not sufficient for everyone just because you feel that way.
You can't make blanket claims that apply to all of humanity; being an absolutist only works if you're a Sith Lord.
