If we extrapolate past pace of AI development, my question is, will the future be a transhumanistic one or a posthumanistic one?
Will man merge with machine, or will the machines decouple from humans and develop independently?

If we consider the transhumanistic scenario, it seems only natural to conclude that we will create the Matrix. At first one single human will connect with a machine, then a dozen, then a hundred, then thousands, millions, billions.

Maybe all big tech players (the magnificent seven) will offer their own version of Matrix, so we can view it as the next, evolutionary step of the internet.

If we consider the posthumanistic scenario, well, I guess it will be beyond our human scope/horizon, at some point the machines will pass the point of communicability.

Synchron Readies Large-Scale Brain Implant Trial

[...]
Synchron's device is delivered to the brain via the large vein that sits next to the motor cortex in the brain instead of being surgically implanted into the brain cortex like Neuralink's.
[...]
In 2020, Synchron reported that patients, opens new tab in its Australian study could use its first-generation device to type an average of 16 characters per minute. That's better than non-invasive devices that sit atop the head and record the electrical activity of the brain, which have helped people type up to eight characters per minute
[...]
Reuters notes that Synchron's investors include billionaires Jeff Bezos and Bill Gates. It's competing with Elon Musk's Neuralink brain implant startup and claims it's farther along in the process of testing its device.

Neuralink's First Human Patient Able To Control Mouse Through Thinking, Musk Says

The first human patient implanted with a brain-chip from Neuralink appears to have fully recovered and is able to control a computer mouse using their thoughts, the startup's founder Elon Musk said late on Monday. From a report: "Progress is good, and the patient seems to have made a full recovery, with no ill effects that we are aware of. Patient is able to move a mouse around the screen by just thinking," Musk said in a Spaces event on social media platform X. Musk said Neuralink was now trying to get as many mouse button clicks as possible from the patient. The firm successfully implanted a chip on its first human patient last month, after receiving approval for human trial recruitment in September.
