Who knows but have you read what OP wrote?

"I just used o3 to design a distributed scheduler that scales to 1M+ sxchedules a day. It was perfect, and did better than two weeks of thought around the best way to build this."

Anyone with 10 years in distributed systems at FAANG doesn’t need two weeks to design a distributed scheduler handling 1M+ schedules per day, that’s a solved problem in 2025 and basically a joke at that scale. That alone makes this person’s story questionable, and his comment history only adds to the doubt.

> and his comment history only adds to the doubt

for others following along: the comment history is mostly talking about how software engineering is dead because AI is real this time with a few diversions to fixate on how overpriced university pedigrees are.
