I don't know about two years' time, but in ten years' time the majority of code will be written by hand. LLMs are like outsourcing to cheap labor was 20 years ago: it's trendy, but when the abysmal quality becomes apparent the pendulum will swing back.

99% of the code will be generated by LLMs but the 1% created/curated by software engineers will still be the most used apps and systems.
