I mean it has improved greatly about as fast as an actual junior programmer…
The overall technology may. A new model may be better than an old model
But a model is fixed
That's the difference
Your model isn't improving
Get ready to jump on the "pay us more for better models" treadmill or get left behind
Even if we say they haven’t, humans also get paid more as their skills/ability improve. If this hasn’t happened for you I’ve got bad news (or your boss is a dick)
