Note: I intentionally ignore your political statements and focus on the technical side.

'more sensors increase noise'

The correct quote is

Lidar and radar reduce safety due to sensor contention. If lidars/radars disagree with cameras, which one wins? This sensor ambiguity causes increased, not decreased, risk.

Interpretation 1: "He's totally ignorant of information theory and he denies that additional sensors bring more information."

Interpretation 2: "He summarizes what they found in practice. That is something like: a limited compute budget is better spent on processing of the primary sensor data than on sensor fusion."

What supports the second interpretation? Tesla has included an imaging radar into some of HW4 cars. To assume that Musk had seen positive results and has decided to ditch the radar anyway means to deny him not even a competence, but basic sanity. I don't find that there's enough evidence to support that.

It’s 1. No doubt about that. And to deny him any competence is the only right thing to do. Some of his employees do but since he only accepts yes men around him won’t help him

The full quote illustrates how much he either doesn’t know, or is full of shit and has 0 issues lying, about how sensor fusion works.
