$2 billion is an insane amount of money even for a major gov software project
And even after $2B it was completely broken and late and required another year and hundreds of millions.
I get the feeling people see thousands of millions of dollars as some abstract thing. You could build an A+ team with 1/100th that cash. Yet it still ends up sucked down a blackhole that's only designed to consume more money.
And there's zero consequences for failure. The same few contractors will get the contract next time.
