Fucking tech bros. Yeah we can do tunnelling way faster and cheaper than anyone else. Sure buddy, as long as you make the tunnels so small they are basically unusable, remove any and all safety features, don't comply with any regulation at all and completely fuck over the environment while you are at it. And they are still slower than regular tunnelling companies and the cheaper part is hard to say with all the shady shuffling of money Musk is doing all the time.
I'm all on board with infrastructure projects taking too long and costing too much because of bureaucracy and nimbys. If we could fix some of those things, sure. But fixing a couple of things doesn't mean re-invent the wheel and make it super shit while they are at it.
Somehow for the past 20 years being a tech company that disrupts a sector almost always comes down to fraud, straight up lying to investors, disregarding regulations, exploiting workers and shady people stuffing their pockets
