Many developers (certainly #opensource people) have a humble attitude towards software. They know how buggy, transient, unfinished, unreliable it typically is.
But if you take one or two steps back and consider the totality of digital infrastructure, you realise how dramatically important it has become and how it is reshaping society at a pace and a depth that is historically unique.
The so-called #techbros know this. Relatively simple tools & algorithmic inventions can have oversized impact.
