It’s not unknown how Amazon can deliver on its low-latency promise. Low-altitude satellite arrays can be substantially faster than land networks because signals travel at the speed of light (signal over copper doesn’t and even fiber slows down due to frequent repeater hardware) and because the overall distance is shorter. Counterintuitive, but the 250 mile vertical round trip is much less than the inefficient path most signals take on the ground.

Here’s an excellent video that uses Starlink to demonstrate how these clusters achieve low latency: https://www.reddit.com/r/Starlink/comments/9voaoa/simulation_of_revised_starlink_phase_1/

I work as a designer of fire sprinkler systems for commercial buildings pays very well, four degree no, the four year schools doesn't deem it worthwhile to teach it all on the job training, all you need is Autocad, Revit, Navis, and Bluebeam ability to get in. The same is true for hvac, Plumbing, and electrical detailers (note the jobs aren't exactly the same knowledge wise but are similar in the fact that four schools can't be bothered to teach it). Many other jobs are the same. In programing if you start early jr. high school by time you get out of high school (if you get good at it) you can get work almost anywhere where there is a niche (shortage of talent). Fire Sprinkler Design is such a field.
