I’m in no way a Theranos apologist. What they did was evil and crimininal because they pushed far ahead of what any moral startup would do. But they weren’t evil solely because their leadership had blind faith in their product. And for all intents and purposes emulating everything at Theranos that made them Successfull, minus the criminal parts, is a good idea. No one was saying “I wouldn’t invest in them, they believe touch in their product” back in the early phases when they where booming forwards. At the same time, if you skip the blind faith, Bill Gates would just be a regular boring rich kid today, never having bought DOS after already sellling IBM, he would have just told them cynically that he weren’t even sure if it would work out and they would have passed him up.
