Yeah. Up until recently my friend was employed in designing chips in this process.
But it's not like they're designing them exactly the same way as years ago - some advancements are not strictly related to feature size and IIRC these new-old chips are considerably more power-efficient.
Certainly true, a 40nm transistor made in 2013 is not the same as one made in 2023. Likewise, a 16nm transistor made in 2017 will not be the same as one in 2027. The power efficiency on the newer wireless SoCs is unreal.
