i have no horse in the race here - but to everyone trashing the 8am-8pm requirement, availability weekends and nights, and 3 year commitment...
this is the tacit/unsaid requirement of every job I have ever had that had real growth, learning, and ownership baked into it. the only difference is VK is being explicit about it in the JD
I'm hiring my next Chief of Staff. You won’t know every field I work in. What matters is how quickly you learn, the questions you ask, and whether you can think from first principles. You’ll help evaluate opportunities and work with founders building consequential companies. Technical background preferred. Three-year commitment. Menlo Park, in person.

Our age needs men and women who have the courage to do good even when it comes at a cost. Draw close to those who are alone, support those who are weary, and seek out those who have drifted away. Have the courage to forgive, to begin again, and to engage in dialogue.

One way to keep these kids in miami: raise entry level wages for these jobs. The local companies offering $60k for a swe who can make 50% more elsewhere is gonna take that other offer.
"When we stop talking about climate change like it's a political issue and start talking about it as a shared challenge that we all need to work together to solve, that's when we'll finally be able to start talking about saving ourselves," write Katharine Hayhoe and Dana Fisher time.com/article/2026/09/21/…

It's true, climate change will not eliminate the human race. Congratulations if you've figured that out. Have you also figured out that climate change will do a ton of damage, and that the more we can reduce emissions the less damage it will do?

A new study finds that burying logging debris, instead of burning it, could store far more carbon and generate billions in revenue for forest-thinning projects.
Graphyte isn't waiting for the theory to catch up. Project Ponderosa in Flagstaff, Arizona, will utilize residual biomass from forest thinnings to create durable CDR credits, establishing a commercial market while delivering an affordable, scalable carbon removal solution.

⚡Emerald AI is transforming AI data centers into flexible grid allies to unlock 100+GW of power for AI while protecting energy affordability and reliability for local communities. After 18 months of demonstrations—across five data centers all over the world—we've entered our commercial scaling phase and are now deployed at multi-MW, full data center scale with customers spanning the world's biggest AI pioneers, global data center platforms, and leading power utilities. We're proud to collaborate with @NVIDIA, @Digitalrealty, @EPRINews, and others to launch the world's first power-flexible AI Factory—roughly 100MW in Manassas, Virginia—later this year, creating the blueprint for a new generation of flexible DSX AI infrastructure that will be good citizens to power grids and local communities. We're also honored to partner with @SantaClaraPower on the nation's first Flexible Load Interconnection Program (FLIP) to provide additional power capacity to flexible AI data centers.
🤝We are so grateful to our incredible consortium of investors, co-led by @EnergizeCapital and @DCVC, as well as to the extraordinary syndicate of leading global financial and strategic investors. Emerald now counts 12 Fortune 500 Global companies as our investors. Many thanks to Series A investors including @NVIDIA, @SamsungVentures, @aramcoventures, @Siemens, @SalesforceVC, @GEVernova, @RWE_AG, @jeraventures, @ADI_News Ventures, @SabanciHolding, In-Q-Tel, @radicalvcfund, @EnergyImpact_, @lowercarbon, Marunouchi Innovation Partners, @EmCollective, @johndoerr, The Olayan Group, The Temerty Group, @EarthshotVC, @collectiveGBL, General Catalyst's scout fund, and others.
🚀This funding will be instrumental as we rapidly scale commercially across the United States and around the world. Our vision is simple: secure larger and faster power connections for AI while making sure AI gives back to the communities that host it. At Emerald AI, we believe that the biggest new user of electricity—AI data centers—can also be the grid's greatest ally, and a boon for local communities by protecting energy affordability and reliability. Thank you to all of our customers, partners, investors, and our incredible team (grateful to the leadership team pictured below Ayse Coskun Mansi Shah Aroon Vijaykar Shayan Sengupta as well as to the whole fantastic team)—this has already been the journey of a lifetime, and we're just getting started
