One challenge is having enough training data. Another is that the training data needs to be free of contamination. For a model trained up till 1900, there needs to be no information from after 1900 that leaks into the data. Some metadata might have that kind of leakage. While it’s not possible to have zero leakage - there’s a shadow of the future on past data because what we store is a function of what we care about - it’s possible to have a very low level of leakage, sufficient for this to be interesting.

Dean du Plessis could tell Zimbabwean cricket had turned a corner by the noise of the crowd. The veteran broadcaster, who was born blind, has forged a remarkable career as a commentator by distinguishing the game’s almost imperceptible audio shifts. He can tell a slower ball has been bowled by the fractional delay before ball meets bat. He can tell if a batter has pressed forward or back by the scratch of spikes against the hard pitch. And, in 2018, he could tell the sport he loved would never be the same again.
