The projects they're attempting take decades. Period. Loon, for example: Two years for a handful of prototypes, two years for LTE functionality and a "real" trial run, two more years for a mesh network so they aren't bottlenecked by satellites, another year for a large-scale real-world trial run (Puerto Rico), and now we're at the present day. Their job now is to demonstrate that they can keep a balloon fleet up long enough and at sufficiently low cost that it's safe to transition an entire country's economy over to the system. That's probably going to take another ten or fifteen years simply because that's how long it takes to show that your system is reliable enough to be core, critical infrastructure. And Loon is just an easy example. Waymo, Brain. Anything to do with healthcare. Etc. There's a reason these things are called "moonshots".
