Yes most modern languages have lost little endiannes and those that kept it use only for the first 100 numbers.

That's because for bigger and bigger numbers you're correctly pointing out that big endian is more useful when saying the numbers aloud since you can often ignore the less significant digits.

My original point was different though:

You can easily render little endian hexdumps equally readable as big endian hexdumps by just writing them in the order that is meant for numbers, namely right to left.

We even align numbers to the right in spreadsheets. That's the same thing.

Look at an old DEC manual (digital Unix, or VMS) and you'll see hexdumps where the numeric part is aligned from center towards the left and the ASCII part is aligned from the center to the right.

With this layout you can easily read multibyte numbers naturally.
