MTBF can’t be used alone to predict failure probability, because product
mortality follows the infamous “bathtub curve”. Products are as likely to fail
early in their lives as later in their lives. MTBF as a scalar value is just an
average.

Yes very good point -however that's where the historical data should come to rescue to help bend the MTBF line into 
this expected "bathtub curve".
