John Crickett resurfaced Joel Spolsky's classic 'The Law of Leaky Abstractions' to push back on the claim that coding agents are just another level of abstraction. Quoting trq212: working at a higher abstraction level has always required understanding the lower ones, and agents don't change this — sooner or later you'll need to know what's underneath when abstractions leak.

A timely counterpoint amid claims that engineers no longer need to understand the low level.
