“At risk of stating obvious, beware of debt in turbulent macroeconomic conditions, especially when Fed keeps raising rates”

“@p_ferragu When there are macroeconomic risks, it is generally wise to avoid using margin loans on any company, as stocks may move in ways that are decoupled from their long-term potential”

“@SamTwits More importantly, I was head of product and led the design of the original Roadster. Eberhard was wealthy and could have risked his money, but was unwilling to do so.”

“My commitment to free speech extends even to not banning the account following my plane, even though that is a direct personal safety risk”

“@SawyerMerritt Starship & next-gen Starlink satellites are key, but much risk lies ahead before those are working at scale”

“@ajtourville Would be great if someday humanity stopped pointing nukes at itself that would destroy almost all life on Earth. In any given year, there is a chance above zero that they will be launched. We are now at the highest risk in 60 years. https://t.co/hSqNeYHNX1 https://www.nytimes.com/2022/10/06/world/europe/biden-armageddon-nuclear-war-risk.html”

“@NASASpaceflight Tiny helium leak (just barely triggered abort), but we take no risks with customer satellites. Standing down to investigate.”

“@Kasparov63 We gave Starlinks to Ukraine & lost $80M+ in doing so, while putting SpaceX & myself at serious risk of Russian cyberattack. What have you done besides tweet?”

“@DavidSacks SpaceX’s out of pocket cost to enable & support Starlink in Ukraine is ~$80M so far. Our support for Russia is $0. Obviously, we are pro Ukraine. Trying to retake Crimea will cause massive death, probably fail & risk nuclear war. This would be terrible for Ukraine & Earth.”

“@RenataKonkoly Russia is doing partial mobilization. They go to full war mobilization if Crimea is at risk. Death on both sides will be devastating. Russia has >3 times population of Ukraine, so victory for Ukraine is unlikely in total war. If you care about the people of Ukraine, seek peace.”

“@BnOrdhaug @yasin_shafiei @thejackbeyer @NASASpaceflight @BocaChicaGal @NicAnsuini That’s the plan. We’re taking a little risk there, as engine isolation was done as retrofit, so not as good as on Booster 9.”

“(And I do think global warming is a major risk)”

“Population collapse due to low birth rates is a much bigger risk to civilization than global warming”

“@Rainmaker1973 Major volcanic eruptions are underappreciated as civilizational risks”

“@Erdayastronaut @SpaceX @Caspar_Stanley @IzanRamos2002 Enabling engines to take the heat without shrouds might save over 10 tons, all things considered. Shrouds are also a risk in that fuel leaks could be contained by the shroud, forming a MOX bomb. Booster is purging all 33 engine shrouds in flight to prevent this.”

“@planet4589 @NASASpaceflight Cryogenic fuel is an added challenge, as it evaporates to create fuel-air explosion risk in a partially oxygen atmosphere like Earth. That said, we have a lot of sensors to detect this. More later.”

“@teslaownersSV It’s a bigger risk than AI, so I’d put it at #1. If these trends continue, humanity will cease to exist.”

“@WholeMarsBlog At risk of stating the obvious, unless something changes to cause the birth rate to exceed the death rate, Japan will eventually cease to exist. This would be a great loss for the world.”

“For those who (mistakenly) think this is a radiation risk, pick what you think is the worst location. I will travel there & eat locally grown food on TV. I did this in Japan many years ago, shortly after Fukushima. Radiation risk is much, much lower than most people believe.”

“@GerberKawasaki We had to shift some Starlink satellite orbits to reduce probability of collision. Not great, but not terrible either. Station & Dragon have micrometeorite shields (ultra high velocity impact absorption), but EVA suits do not, hence higher risk for spacewalk.”

“@vincent13031925 This is a risk, but not yet a limiting factor”

“Population collapse is potentially the greatest risk to the future of civilization https://t.co/VVN8kElTlS https://www.wsj.com/articles/u-s-population-growth-slows-birth-rate-decline-economic-risk-11627231536?ns=prod/accounts-wsj”

“@skorusARK Cars today are far more complex than Model T, with a global supply chain that is vulnerable to force majeure risk. Like Model T, supply chain for battery EVs simply doesn’t exist at massive scale, so must be built in parallel. Ideas are easy, production is hard.”

“@Teslarati Large pouch cells undergo significant volumetric changes at high state of charge. Even so, fire risk is probably less than gasoline cars. There are over 200,000 combustion engine car fires every year in US alone. It’s literally in the name. https://t.co/uJPlB3IbzQ https://www.nfpa.org/-/media/Files/News-and-Research/Fire-statistics-and-reports/US-Fire-Problem/osvehiclefires.pdf”

“@Kale6360gmail I’m actually 3000 years old, but, at the risk of being immodest, I think I look good even for 2500 years! Still have my original chariot license in papyrus …”

“@leastImAlive @PPathole Yeah, sold my houses, except for 1 in Bay Area that’s rented out for events. Working on sustainable energy for Earth with Tesla & protecting future of consciousness by making life multiplanetary with SpaceX. Also, AI risk mitigation with Neuralink & fixing traffic with Boring.”

“@TrungTPhan Had no money to invest in Zip2, but my founder equity yielded ~$15M after tax. Of that, I rolled ~$10M into PayPal, which yielded ~$180M, then … Basic principle is that I would not ask investors to risk money on my company if I would not also do so.”

“@ajtourville @Erdayastronaut @SpaceX Yes, but engines have a min throttle point where there is flameout risk, so landing on 3 engines means high thrust/weight (further away from hover point), which is also risky”

“This is a life leader launch, so more risk than normal”

“@WholeMarsBlog Berlin will use 4680 cell with structural battery pack & front & rear single piece castings. Also, a new paint system. Lot of new technology will happen in Berlin, which means significant production risk. Fremont & Shanghai will transition in ~2 years when new tech is proven.”

“@l_vaux @kulpability @tlowdon @EthicalSkeptic People are extremely unlikely to die of Covid/sars-cov2 alone. If you have multiple pre-existing health conditions & a weak immune system, then you have significant mortality risk from many diseases (not just Covid/sars-cov2) that would otherwise have minor effect.”

“@universal_sci Asteroid impact risk is well understood, but not comets. Those worry me.”

“@engineers_feed Falcon/Dragon are designed to withstand multiple lightning strikes, but we don’t think it would be wise to take this risk”

“@Commercial_Crew @NASA @SpaceX Proceeding with countdown today, weather cancellation risk ~50%”

“@OfficialAPoD @joerogan Pain can certainly be turned off, but we’re not sure what the best initial test case (max goodness for least risk to patient) would be quite yet”

“@Robotbeat @ghotiing @CruizVinicius @josh119872 @SweetINXS @voteLabonte @Erdayastronaut @Tesla Tesla actually sent out ResMed, Philips & Medtronic units. Latter is fully intratracheal. My personal opinion is that some ICUs are jumping the gun on intubation & setting PEEP & O2 too high. High pressure, pure oxygen increases risk of lung damage. https://t.co/2IUnS5DPOg”

“@CDCgov Close contact family gatherings that mix young kids, who have almost no risk of C19 death, with grandparents who have high risk (especially those with prior lung damage), are one of the most powerful mortality vectors”

“@MG42bonesaw A single computer, pump & pressure accumulator would be fine for many patients, but ideally individual valves per patient to personalize care & avoid cross-flow risk”

“@Erdayastronaut @SciGuySpace Last launch aborted due to slightly high power. Possibly, but not obviously, related to today. This vehicle has seen a lot of wear, so today isn’t a big surprise. Life leader rockets are used only for internal missions. Won’t risk non-SpaceX satellites.”

“@flcnhvy @SciGuySpace F9 iteration slowed down as payloads became too important to risk. Little change is expected going forward with F9/FH or Dragon. Starship production & thus iterative improvement will be much faster than Falcon. Driving hard for fully reusable orbital flight this year!”

“@CathieDWood @sbarnettARK @jwangARK @ARKInvest First, we need to make it super safe & easy to use, then determine greatest utility vs risk. From initially working to volume production & implantation is a long road. As with vehicle safety, it will be much harder to pass our internal standards than minimum regulatory standards.”

“@IrinaAntony @tjq1190 @tyger_cyber @fawfulfan @_Mikemo We started Zip2 with ~$2k from me plus my overclocked home-built PC, ~$5k from my bro & ~$8k from Greg Kouri (such a good guy — he is greatly missed). My Dad provided 10% of a ~$200k angel funding round much later, but by then risk was reduced & round would’ve happened anyway.”

“@Jason @kylegrantham Making a roof out of kindling in a fire risk zone is not recommended”

“Worth reading “Human Compatible” by Stuart Russell (he’s great!) about future AI risks & solutions https://t.co/ZCdvZrrcVf https://www.amazon.com/Human-Compatible-Artificial-Intelligence-Problem/dp/0525558616/”

“@pbreit @PatrickLac007 @AngelGPonce @Tesla Yes, but owner will have to accept tiny risk of damage. Those are very hard even for careful human drivers.”

“@Erdayastronaut @Tyler0309 @TheVondo About right, but dangerously chuggy & risking bad things at 40%. We’ll keep it above 50% for this flight.”

“@flcnhvy @Malcolmmarsman @marstronauts @Erdayastronaut @JaneidyEve @13ericralph31 @SPEXcast @bluemoondance74 @Orion_Sword @Some1gee @SpaceX First flights would have fewer, so as to risk less loss of hardware. Probably around 20.”

“@FredericLambert Fred, every fire *is* investigated. Problem is those who only write about 0 injury Tesla fires while ignoring fatal combustion car fires or fail to mention any contextual statistics in their article, misleading readers into thinking EV’s have high fire risk when opposite is true.”

“@CdeCiencia First flight for Falcon Heavy Block 5 means there is some risk of failure between 5% to 10% imo. Many good design improvements from Falcon Heavy demo, but the changes are unproven.”

“@nextspaceflight Yes, lot of risk”
