From what I saw, the hyped Boring tunnel cost savings he demoed were by comparing the cost of the tunnel he had built to the cost of a complete station. Comparing apples to apples, it's competitive, and that's an achievement in itself, but they haven't proven anything like the savings he claimed. That's a recurring theme with Musk's hype. It's great that he's taking a fresh look at these things, and in some cases he's found some genuine efficiencies, but the expectations he puts out is that the rest of industry is locked down into hopelessly obsolete and inefficient methods. That's just not true, but it's a very appealing story.
