"Far from just being the product of our parents, scientists have now shown that widespread transfer of genes between species has radically changed the genomes of today's mammals, and been an important driver of evolution."
The way you define focus sounds a bit strange to me. Focus is indeed needed for programming - that's why you need to be in the zone when coding - but it's the focus we refer to usually.
As we live in a frantic attention economy now focus is indeed very valuable as dealing with the ongoing bombardment with distractions is truly expensive.
Just think about all those remote workers getting reminded all the time that some new Slack, Flock, Skype, WhatsApp, Facebook, e-mail messages arrived.
All the companies above make money by hijacking our attention and forcing us to focus on the work we do for them for free instead. Imagine us focusing at the code instead.
