Musk provided few details about the surgery, which had to be postponed after the patient originally scheduled for the second procedure had to withdraw in June due to an unspecified medical condition.
???????? This sentence appears to be crafted to perfection: make these details as boring as they could possibly be so no one asks questions
And this Musk quote regarding how the procedure went:
“There’s a lot of signal, a lot of electrodes.”
That's devoid of information.
Perhaps I should listen to the podcast. This article mostly told me what a podcast said.
