“@EPavlic @breckyunits @bchesky Just leaving Tesla engineering offices in Palo Alto. Mostly good, some bad. The future is going to be wild. There will be so many robots …”

“@Teslarati @KlenderJoey I’d like to express appreciation to Tesla Autopilot engineering & QA for working round the clock all weekend to resolve the problem”

“@Teslarati Rawlinson didn’t design Model S. Prototype was done before he joined & he left us in the lurch just as things got tough, which was not cool. He did make some contributions to body/chassis engineering, but not to powertrain, battery, electronics or software.”

“@amir Can’t believe you’re even writing about this. My job as CEO is to focus on what’s most critical, which is currently Model 3 production. Doug, who I regard as one of the world’s most talented engineering execs, is focused on vehicle engineering.”

“@pbeisel AI5/AI6 engineering is my biggest time allocation at Tesla. AI5 will be good, AI6 will be great.”

“@WholeMarsBlog FSD is best in Bay Area, given engineering mostly lives there, but rest of country will soon be at that level”

“@teslaownerssv It will get absurdly good. Tesla AI/Autopilot engineering is awesome! There’s some great AI out there, but can it self-drive while playing Cyberpunk … ?”

“@Teslarati @ResidentSponge It is an electronics/mechanical/software engineering problem for the Neuralink device that is similar in complexity level to smart watches (which are not easy!), plus the surgical robot, which is comparable to state-of-the art CNC machines. No need for AI/ NN/ML quite yet.”

“@EvaFoxU @Tesla Berlin Model Y is the one to watch. That is a revolution in automotive body engineering (finally).”

“@Scobleizer @Tesla @teslaownersSV 🖤 Tesla Software Engineering 🖤”

“@teslaownersSV @iamyesyouareno @MarioNawfal The specific area I’m talking about is engineering, which is needed to build the best technology. Encouraging kids to learn how things work is the key. Take apart car engines, toasters, microwave ovens, speakers, etc. Make model airplanes, rockets, cars. As you’re doing this…”

“@Teslarati Model Y heat pump is some of the best engineering I’ve seen in a while. Team did next-level work.”

“@WholeMarsBlog Tesla has great respect for software engineering, they do not”

“@DimaZeniuk @truth_tesla That’s a low bar. Carmakers have never valued software engineering highly, although VW is trying to change that. I personally wrote software for 20 years & have huge respect for software engineers. Tesla is on par with best software companies & is leader in real world AI.”

“@MeetLuis @WARREZ420 @WholeMarsBlog Rawlinson was never chief engineer. He arrived after Model S prototype was made, left before things got tough & was only ever responsible for body engineering, not powertrain, battery, software, production or design.”

“@SamTwits My true moral error was creating Tesla & SpaceX at same time, while avoiding general mgmt chores at Tesla (focusing only on product & engineering). Tried to have my cake & eat it too, which failed.”

“@teslaownersSV @SamTwits He came damn close to killing Tesla through a combination of bad management decisions, driving out talented people, bad engineering, major blunders in supply chain & an elaborate deception about the true cost & schedule of the Tesla Roadster.”

“@iamacloudguy @Model3Owners Good news on this front. Tesla engineering rallied & this will be part of V9. Going through final testing now.”

“@Teslarati Great work by SpaceX valve engineering & production!”
