Why didn’t the Romans mechanise their fields with water wheels or the Egyptians roll their stones on wheels instead of dragging them? History points to economics: labour was cheap. With slaves, serfs, and vast conscripted workforces, there was little incentive to replace human effort with machines. History suggests that technological adoption is not simply a function of what is possible, but of what is economically necessary. Fast forward to today. We live in a world where labour is expensive – at least in advanced economies. Hiring talent is costly, regulations surrounding human resources are strict, and demographic trends indicate a shrinking working-age population in many countries. Unlike the Romans, we do not have limitless human labour. Enter AI. From Empires to Enterprises History is littered with examples of innovation stagnating when labour was abundant. (Perhaps unsurprisingly, given humans’ innate aversion to change and the disincentive for the ruling ‘elite’ of any age to implement change lest they lose control. Ancient Egypt: They had the wheel, but they didn’t use it to build pyramids because dragging stones with cheap, abundant manpower was simply more “cost-effective.” The innovation was available, but the incentive wasn’t. Roman Empire: Romans knew about water power, yet grain was still ground by hand on a massive scale. A water mill could displace hundreds of slaves. But why build it when labour was plentiful and cheap? China: China discovered gunpowder centuries before Europe, but didn’t weaponise it as fast as building labour-intensive armies was easy and viable. The Ottoman Empire: Failed to adopt the printing press as widely as Europe, as scribes where cheep and cultural barriers delayed its adoption. Mesopotamia: Had the arch, but didn’t realise its full potential, using it only in small buildings like tombs, because labour (slaves) was cheap and projects were small. (The Romans, by contrast, despite equally abundant labour, faced massive infrastructure demands across an expansive empire, requiring efficiency. This need for solutions above the capacity of…
We have AI. The question is whether we will be Romans ignoring the water wheel or entrepreneurs harnessing the steam engine.
