6.5 X 15 is only 97 hours per week not even close to the 400 hrs (5X40) per week of programming a 10X Rust programmer can provide. I jest but all this 10X stuff is getting ridiculous. They stayed in "Stealth" mode because they didn't have anything worth showing for 5 years. Doesn't sound all that productive to me. More likely what they are trying to do was hard and complicated and took a while to figure out.
They're not boasting about their current productivity, they're boasting about the one they achieved at FoundationDB when they implemented the testing, which gave them the idea to build antithesis
