@jake_bittle omg you're right, they should adapt the classic novel FRINDLE, which had a huge impact on how I and my generation thought about technology, and was also emotionality devastating

Had a Jane Street phone interview in 2016. "Price a 6-month forward on carrots."
There's no carrot futures market, so I build one from scratch: seasonal harvest cycles, USDA demand elasticity, cold storage decay rates.
One trader stops me. "Your storage cost function– you're modeling the carrot as dead inventory. Like grain in a silo." He asks me the metabolic respiration rate of a post-harvest carrot at 2°C. I estimate.
"Your forward is overpriced by exactly that shrinkage. The underlying is consuming its own sugars. It's alive." Good correction. I adjust the model. I think I've recovered.
Rejection email comes the next morning. Subject: "Ethical Review." My framework, they write, "relied on the severance of the root organism from its growth medium." The question about respiration was a test. The carrot was still alive and I'd built an entire derivatives structure on top of its death without questioning whether harvest was an acceptable act.
I pull up the recruiter's original email. It doesn't say Jane Street. It says Jain Street– a non-violent quantitative commodities fund.
The carrot was never supposed to be priced. It was supposed to be refused. I later learn the only candidate who passed that round was a former monk from Gujarat who sat in silence for eleven minutes and said, "I cannot put a price on life." He's now a partner.

@taste_of_tbone As of today (4/27/26), Skenes has faced 1357 MLB batters & has allowed 23HRs, or 1HR per 59 batters. He avgs 4.10 pitches per batter. So 100 pitches= ~24.4 PA. So per 100 pitches, *BIG LEAGUE BATTERS* have avg'd ~0.41 HRs against him. Couchsitters like us have absolutely no shot.
