I beg to differ. Stuttgart 21 underground train station [1]: Estimated cost 2009: €4.5 billion. Estimated cost 2022: Over €9 billion. Estimated start of operation: Six years later than anticipated (2025, or 15 years after construction started). Another, recent example: German Cyber Threat Reporting Center that is supposed to report cyber threats to NATO is still not operational after five years and €60 million. Admittedly, not on a billion dollar scale, but the example shows how even a relatively simple task like creating reports is plagued by overruns.
