Break a comparison
You are not the next Severin Hacker.
That is not pessimism. It is precision. You can study this path, but you cannot inherit its conditions, replay its sequence, or schedule its luck.

ETH Zurich (elite European CS) to CMU PhD under Luis von Ahn — a rare mentor-cofounder pipeline. Von Ahn's advisor relationship became a cofounder partnership at Duolingo, combining elite institutional access with a high-trust team formation.
Two forces, no new scores
Perseverance and luck both matter.
Documented perseveranceHacker paired elite European CS training with a high-trust advisor relationship that became a cofounder partnership.This records repeated behaviour or recovery described by sources; it is not a grit or merit score.
Luck and unobserved varianceNo discrete luck event is documented in the reviewed biographical summaries.A successful-only archive cannot recover all encounters, avoided setbacks, or alternative outcomes.
Sequence matters
These conditions arrived in this order.
A different order is a different path—even when some ingredients look familiar.
