That's certainly part of it.   I can also read and absorb text much faster
than plowing through some interminable video presentation.

And in some working enviroments, I don't have the ability to view video.

The relationship between executable size (presuming that any cruft like
exception tables, debug symbol tables, run-time loader symbol tables, .rodata, .data,
rtti tables, etc. are not considered when calculating executable size) and i-cache hit
rate is minor, if it exists at all.    Far more important is the size
of the text section 'working set' (to borrow from the old VAX days).  There
may be a zillion pages of infrequently used text, which will never get
into the Icache at all during normal program operation.

I'm with you.
