England with 3 million people in 1500? The counterfactual AI can't solve

England with 3 million people in 1500: the demographic experiment nobody ran

The idea that an England with three million inhabitants in 1500 would have accelerated its development sounds good on paper, but it is an exercise that confuses correlation with causation. Google's AI generated three scenarios —3.0, 2.7 and 2.5 million— in which demography acts as an independent variable, as if history were a video game slider. The problem, as a critical analysis pointed out, is that the Black Death was no common cold: it wiped out between a third and half of Europe's population. To reach those figures, the plague would have had to be less virulent, which changes the whole baseline of European history.

The sweet spot that doesn't exist

The 2.5 million scenario is presented as the «perfect balance»: no subsistence crisis, no radical geopolitical shifts, just an England that moves its development forward a few decades. But the critique notes that 400,000 extra mouths can also miccionan 400,000 problems with public order, inheritances or conflicts over resources. Agricultural productivity was still that of the Roman plough, and the fiscal surplus depends not only on the number of taxpayers, but on what they produce and how much can be squeezed out of them without triggering a bread riot.

The Black Death was not the trigger for the end of feudalism

Another cliché the counterfactual repeats is that the plague «accelerated» the decline of feudalism, the Renaissance and Protestantism. In reality, English feudalism had already been faltering since the thirteenth century due to demographic pressure and the exhaustion of marginal lands. The mass mortality upended the lord-peasant relationship as labour became scarce, but the nobility responded with the Statute of Labourers of 1351 to hold down wages. History is not a linear function.

Balconies to air out the counterfactual

Among the comments, one sharp jab stands out: «If only the Spanish had gone over to build them balconies». The joke contains a real criticism: the poor sanitary conditions of medieval England contributed to the spread of the plague. But it is also a reflection on how each culture manages its spaces —and its corpses—. A reminder that demography does not explain everything.

With all this in mind, the next time an AI attempts a counterfactual, it should ask where those people came from before telling us what happens next. Perhaps then alternate histories will stop being statistical toys.
