This reminds me of a close friend’s story…
Almost a decade ago, one of my best friends worked in Tesla’s self-driving group, at the time under Robert Rose [1]. The compute hardware in the Model S was underpowered, so Rose chose to use Greenhill’s RTOS on that hardware rather than Linux.
Musk fired Rose for using Greenhills instead of Linux, and took direct control of the self-driving group (worst-case result, which all the managers were trying to avoid). (I believe they’re since upgraded the compute hardware twice since. Rose was, of course, right)
Anyhow, my friend was in charge of some other aspect of the system, and was trying to obtain server hardware for their work.
It took them a year to get the budget and purchase request and provisioning for the server hardware they needed to get the work done. As an external observer, it was completely flabbergasting to see the contrast between Musk’s outlandish expectations and Tesla’s financial bureaucracy.
My friend was, and still is, someone who will endure unreasonable pain in the pursuit of interesting goals (I admire them greatly for it but also know when not to follow them)
They eventually went directly to Musk (who was at this point basically their direct manager) to ask for more server hardware, and instead Musk completely steamrolled them about how they weren’t agile enough (I’m avoiding technical details for anonymity, but this is a topic that you mathematically cannot avoid hardware on).
I don’t remember if that was exactly my friend’s last day, but they left Tesla around that time. There was nothing to salvage.
I’m honestly impressed that Tesla has made any progress on self-driving, but it’s obviously done in spite of Musk, like trying to build a Lego tower around a baby throwing tantrums.
