Not sure if I'm being cheeky but "augmentations" like this have existed for millennia.

Most recently, smartphones, or more generally the internet, have made it so anyone can know basically any information they need to, on demand, almost all the time. Some functions, such as calculators, don't even need the internet.

However, we can go back further. I'd say the first technological enhancement of human intelligence was writing, vastly improving the memory of anyone who uses it.

We may not be physically implanted with machines, but humans have been using technology to augment their intelligence almost as long as technology has existed. And honestly, the capabilities we have right now are probably nearly as effective as whatever the optimal version is, at least if they're used correctly.

You may not feel any smarter, but the end result is the same. The system comprised of you and everything you carry is much smarter. Similar to the [Chinese Room.] (https://en.wikipedia.org/wiki/Chinese_room)
