Reliability is not the same as completeness and this is very, very important

Apparently it can spot sharks with a 92% reliability rate. Now, as I understand the term "reliability", that means that 92% of the things it identifies as sharks will actually be sharks. Which is quite different from saying that it has a completeness of 92%, in which it manages to spot 92% of the sharks present.

Also, it can drop a floatation aid to help swimmers. Very good, but this means the next version of Baywatch will have the lowest ratings of any TV show ever.

    Wait 'til the sharks have anti-drone "L.A.S.E.R beams" attached to their heads.
