>>you can't simply put up a bridge that would support 500 cars and say "oh we'll update it to support 5000 cars down the road"
In that case the requirement changed, it might require some extra support or upgrades to the bridge, if not we have to build the bridge all over again.
Similar in SWE, the requirement can change, if you planned a small MYSQL database to hold 2 Stores transactions and then "oh well we will need to support 2000 Stores Transactions" you might try upgrade the server or start from zero on a AWS cloud instance that keep up.
In SWE you still have the big decisions than can impact people and budget, a bridge can collapse, so the autopilot software can make the car crash
