Why Reading English Feels Painfully Linear: Transitioning from Subvocalization to Parallel Chunking
Why native Chinese speakers scan paragraphs effortlessly in Chinese yet regress into word-by-word subvocalization in English. An engineering inquiry into orthographic decoding, visual fixation vs. cognitive attention, and structural chunking.

Fresh out of college, I thought great engineering meant writing the cleverest algorithms and abstractions. Four years in, code is the cheapest byproduct; the durable value lies in respecting the actual problem and closing the loop end-to-end.
