What is the cumulative total number of hashes computed by all the bitcoin miners of the world since the beginning of times (i.e. genesis)?

My rough estimate: 3.84e28

Which is high enough that finding a hash with 24 leading zeros becomes quite likely.

(The smallest hash found so far is of block 756951 with 24 zeroes

My estimate is just summing up the last 6 years with an estimate avg hashrate for the year)
