One of the things the eSafety Commissioner talks passionately about – and I come to agree with – is a concept she calls ‘safety by design’. Her idea is that instead of being retrofitted after the damage is done, tech platforms must be engineered to protect us from the get-go. This strikes me as just like cars fitted with mandatory seat belts and airbags in case we crash while driving them. Late at night when I’m writing and peeling back all the painful consequences of predator trolling, I can’t help wondering how different things might have been. How many lives might have been saved if social media companies had, right from the start, internalised the Latin phrase all medical students are taught, primum non nocere? First, do no harm.
