I think the whole reason AI has become what it has is because these are “brute force” things you can’t do with a normal CPU. So functional programming and massively parallel algorithms are what make it possible.
Every year it gets more accessible to a wider audience. Soon there will probably be frameworks that hide the complexity completely and you can just say here’s a massive dataset, I want to train it to be a conversation bot or cat pic classifier, go. But we’re not quite there yet.
