because the sensor wears out after 10,000 clicks
Utter baloney. Blown out highlights are due to incorrect exposure. The solution is to learn how to read the histogram and not overexpose the image on a sensor that has a smaller latitude than negatives.
I don't think there are any reliable answers as to how long DSLRs last since I've run into DSLRs (of the medium format kind) that are well past 5 years old (I cannot even imagine the # of exposures on these pro units).
