Okay, here’s the scary reality of writing software: It’s like building a railroad from Chicago to Los Angeles. Everything’s hunkey-dorey until you get to Denver and go: “Who put a MOUNTAIN RANGE here?”.
Sad part: A project manager would look at the above and say, ‘well, we’re halfway there, and it only took us 6 months so far, so you should be able to surmount…um…whatever’s in the way from here on out…in 8 months. Work overtime. Think outside the box.’
The mountain remains unimpressed.
