Good app but racist timeline – Computer Science Guide Review

The app itself is good, with great terms, a nice UI and is very user-friendly. The timeline of math/computer history is horrific - it speaks of the brilliant math/tech inventions of the Babylonians, Persians, Chinese, Arabs, Indians and Europeans, but literally skips over the predating dark-skin cultures (Egyptians, Sumerians, etc) in the cradle of civilization who invented the foundations of math, engineering, astronomy, etc. Ancient batteries, ancient machines, how the Egyptians revolutionized the chariot (it mentions the South-pointing Chinese chariot of course), where zero numerically was used before the Indians, Egyptian use of a binary system, Egyptian cryptography, ancient Sumerian astronomy devices, etc. I could go on and on, are curiously skipped over. Modern history? A woman was one of the first programmers of the computer. Black American Dr Marc Dean of IBM invented IBM's Official PC and 1 Ghz processor and holds the patents. A Mexican PhD invented one of the first brain-computer interfaces. These facts are not in the timeline. Why?
