After years of disregarding @emilymbender.bsky.social (and those of us who develop physically-based models), will any CEOs, politicians, or government officials listen to a DARPA PM invoking her language to ridicule the "plan-shaped object" machine?

www.nationaldefensemagazine.org/articles/202...
Eric Davis, program manager in DARPA’s Strategic Technology Office, said his entire $250 million portfolio consists of AI-related projects. However, “there's not a single large language model in the work that I'm doing right now,” he said during a keynote speech at the National Training and Simulation Association’s MODSIM World conference. “We're told that generative AI is going to design our supply chains. It's going to coordinate our disaster response, run our power grids, do our homework for us,” he continued. The technology has massive potential, but it cannot solve every problem. Large language models can ingest vast amounts of data and produce well-articulated outputs that maximize one thing: human approval. “That's why what they say is so convincing,” Davis said. “What they lack are internal models of causal reality.” These models don’t understand concepts like gravity, fluid dynamics or fuel consumption. They don’t understand how diseases are transmitted or the laws of thermodynamics. “If we ask an LLM to output a plan, we get a very convincing language-shaped, plan-shaped output. But whether it's for wildfire evacuation, a hospital surge or military planning, what it's not based on is reality,” he said. “And if we trust that plan to be truthful, we will be disappointed.”

MODSIM FOR ENGINEERS
MODSIM FOR ENGINEERS INTRODUCCIÓN: What is MODSIM? MODSIM on Dassault Systèmes’ 3DEXPERIENCE® platform is a unique next-generation engineering & design paradigm that completely unifies modeling and simulation. This merging of two traditionally distinct disciplines provides opportunities to significantly accelerate design exploration, optimization, and validation, and canalso unlock new innovations. Since the design model is also the virtual twin used for simulation, MODSIM returns analysis much earlier in the development cycle, before any physical testing has been done.

I am attending the ModSim conference for the first time next week, and I'm presenting analysis and design modeling of I/O performance requirements for frontier model training based on a year's worth of production data across the VAST hyperscale fleet (>900 training jobs, >140K GPU-years of compute)

With more higher ed programs offering dedicated data science and AI degrees, I'm wondering what value employers will see in hiring a physics major over someone whose whole of undergrad focus was generating "models" (not in the modsim sense).

You've still got time. I have three books on my desk in my ModSim office - the Art of Wargaming, the Craft of Wargaming, and Forging Wargamers. It's a fun stack to provoke conversation among a select group of visitors. Still looking for an Army book. Y'all under the USN get all the good books.

Compound AI is changing how we train, team, and win.

At MODSIM World 2025, Aptima’s Svitlana Volkova showed how Human Digital Twins and agentic AI simulate, evaluate, and optimize human teaming and information ops to give commanders decisive pre-mission advantage.

On the MBA vs MBP question, I’d go back to what you’re likely to be doing.

If it’s a travel and leisure machine with some productivity/code, the air is more than enough.

The pro is mainly for *many* external displays, or large, continuous workloads (think games, large modsim, big compile jobs)
