Clearly these men never raised a baby, or they may well be fathers but never really had anything to do with their kids because pretty much any mother will tell you why language was invented - so we can communicate basic human needs. Most mothers have experienced the frustration of trying to figure out what is the difference between a cry of pain, hunger or discomfort. That discomfort may come in a multiple of varieties, meaning diapers need changing, extreme tiredness, perhaps even boredom, or the need for exercise... and yet the baby has only one mode to communicate all of that - crying.
Anyone trying to communicate with a child learning language knows the frustration of trying to figure out what the kid is saying when their sentences are ill formed and they still can't pronounce certain sounds.
Yet men think language evolved so we could express profound thoughts? I do not think so.
Men's genius at understanding simple things is often staggering and isn't limited to language, let's have a look at how men think learning happens. In this article the awful technique of training artificial neural networks is discussed.
The skinny on training artificial neural networks is you expose the neural network to the same examples over and over again until the artificial neural network kinda repeats what you showed it back at you - and by 'kinda' i really mean 'kinda'. This is nothing like how humans learn - yeh okay you may not remember the letter 'g' the first time you see it and are told it's a 'g' when you're a child, but you don't have to be told upwards of 2000x unless you have some kind of learning disability, and when I said 'kinda', you wouldn't be happy if you told your child it's a 'g' and the child came back and said it's probably a 'g' but it's only 78% certain. You might find that pretty exciting because we know in our heart that nothing is certain, but the reality of human learning is a 'g' is a 'g' - that 78% is definitely meant to be 100%. But artificial neural networks, despite all the hype really aren't that good at simulating human learning. Meanwhile that 78% that the neural network has learned comes at the expense of learning the letter 'z' and 'q' - which are quickly forgotten by the neural network because they don't appear very often - and the 78% certainty of it being a 'g' doesn't even mean something as sophisticated as the neural network getting it confused with an '8' either.
Yet AI is being hyped as the next best thing since sliced bread. Probably because those of silicon valley believe that the first to market - which is probably true unfortunately because customers can play follow the leader because they know they aren't experts. The reality is, the experts aren't experts either.
