Apple products are fine, generally well built and easy to use, especially if you value multiple interconnected devices.

Depends on the intended use.
Human/brain interfaces have tons of potential for helping people with injuries to their central nervous system. Someone could eventually regain the ability to walk with just a few chips and electrodes.
However if it’s like “fuck yeah I wanna mainline the Internet” then yeah, that shit sucks.
Of course Elon owns the company, so it’s bound to be the stupid thing.
