The framework will change.
The layer under it moves slower.
Everyone learns the tool on top.
The people who last
also learn the thing it's hiding.
The ORM comes and goes.
SQL stays.
The framework churns.
HTTP stays.
The library gets rewritten.
The data structure underneath is the same one from 1970.
Abstractions are a gift —
until they leak, and they always leak.
When they do,
the person who knows the layer below
is the one who fixes it.
Chase the fundamentals.
They're the only thing nothing deprecates.
– Serguey Asael Shinder
