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.

“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.
