there's some unique dysfunction where the cos with the largest AI budgets move really slowly due to people-coordination problems
so an avg eng spends $5k / mo on tokens but you can't get something thru procurement in <3 mos

when you increase throughput at somewhere that is not the bottleneck
you do not increase the throughput of the overall system

At @mastra we have a value: "the right thing to do is the right thing to do."
One thing we realized: we're pragmatists, not philosophers, not pedants
We don't debate trolley problems, or sit around arguing tabs vs spaces
We do trust our technical, and our moral, intuition
