You're an early adopter, so you're seeing massive gains. But eventually everyone gets the same productivity boost and that becomes the new baseline expectation.

Any clever prompting techniques that give you an edge today will evaporate quickly. People figure out the tricks, models absorb them, and tools automate them away.

There's no substitute for actually coding to learn software development. For new engineers, I'd strongly recommend limiting AI code generation on real work. Use it to explain concepts, not do the work for you. Otherwise you'll never develop the judgment to know what that 10% actually is.
