What does your construction industry do if not "construct" those things? Have they devolved to just being lego builders that glue together the work of others?
um, yes? Home building construction crews are not the ones making doors, or windows, or tubs/faucets/etc. They buy them as parts to be assembled into a whole. What did you think that the crews are pouring glass on site into windows, or firing up ceramic glazing ovens to cure the toilets and sinks?
What a strange comment on the Hacker News, where everyone uses IDEs, debuggers, toolchains, profilers and other higher-level instruments to build products. When have you written your own hardware driver?
How many programmers do the low-level work on the "doors and windows" stuff? A tiny minority.
