Some reasons to measure

Dan Luu argues that measuring things is often more valuable than building them, because measurement is undervalued and high-impact measurement projects are easy to find. He cites Kyle Kingsbury's Jepsen work, which found serious data-loss and consistency bugs in many distributed databases, such as Redis Cluster losing 56% of writes during a partition and RabbitMQ losing about 35% of acknowledged writes. He also says that published measurements led to improvements in keyboard latency, Consumer Reports headlight testing, and Tesla Model 3 braking distances, which improved from 152 ft. from 60 mph after Consumer Reports and Car and Driver tests. Luu says his own measurement work is driven mainly by curiosity.
