This argument doesn't make any sense. It wasn't a beta, nor an alpha, nor anything.
It was just a marketing gag without any substance or technology. As part of an alpha or beta, you need an actual pathway to a full release.
There was literally nothing. If this were released as a beta after having raised lots of money, people would call this a scam outright, because it didn't do anything new or more efficient.
I don't think this is true. There are blood tests that don't always work. Lyme disease is one that is not accurately detected.
False positives and false negatives will occur with all testing and there are protocols in place to detect false readings. While most tests are accurate, an inaccurate result is not considered a mistake since the tests themselves are not perfect. (Given that you followed proper procedure)
As the founder of a healthcare company, Tim's statement here is the one that I found the most dangerous
"If all she had to do was say this was a beta or whatever and all of us would be using it, would be loving it."
When it comes to people's health you must have concrete evidence that your product works and is robust. Blood testing is not a field where people accept mistakes. Anyone working in this field is used to scrutiny, it is your burden to prove that what you are working on is safe and useful.
There are a lot of quacks, hucksters, and fakes out there proceed with caution.
