You literally don't know what you're talking about, and your own list proves it.
James Webb / Artemis? SpaceX reaches space at 1/10th of NASA's cost. Rocket Lab and Blue Origin are launching scientific satellites with private money at efficiency levels your government agencies could never dream of.
LIGO and the Large Hadron Collider? Billions spent on particles with zero practical application to this day. Meanwhile Google and IBM built quantum computing with private money and results you actually feel in your daily life. You're welcome.
Human Genome? That's literally the worst example you could have picked. Celera Genomics a private company completed the exact same work for $300 million vs the $3 billion the government burned through, and finished faster. You just cited an example that destroys your own argument.
Operation Warp Speed? Did you know Pfizer explicitly refused government funding? They developed their vaccine entirely with private capital, and it was the fastest and most effective one. The government wasn't part of their success story.
ITER
A project that started in 1985, still not operational, 20 years behind schedule. Meanwhile Helion privately funded already has a contract with Microsoft to sell energy by 2028, and Commonwealth Fusion is targeting a working reactor by 2030. The private sector will achieve nuclear fusion before your government megaproject does.
National Ignition Facility
$3.5 billion to achieve ignition once under controlled lab conditions. Helion is moving faster with a fraction of that budget.
NOAA Climate Modeling
Google DeepMind built GraphCast more accurate than every NOAA model after decades of government development, and 1000x faster in computation.
