Putting the sort into "ls" makes the binary (a little) bigger. Having just one sort tool probably saves space, especially when memory is precious like it was 40+ years ago. That's the fundamental concept in *x: have small specialized tools that do one thing, but do it well.
tac doesn't sort, it just reverse the order of lines.
Besides convenience, command line tools got more options because they are much more powerful these days. Just compare rcs vs. cvs vs. svn vs. git.

Must have mis-read my calendar
Hm, is the intelligent part the amoeba or actually the neural network coaxing them towards the solution?
What a f***cking complicated way to listen to your favorite FM station.
Whole Trade Banana: 30 cents, Lean Ground Beef: $2 - that can't be good for neither the environment nor the people nor the animals.
Much better: buy locally produced stuffed, pay fair prices, eat less meat.
No way to help those guys
Thus mathematics may be defined as the subject in which we never know what we are talking about, nor whether what we are saying is true. -- Bertrand Russell
