It's not always about race, there are a great number of people that look at people and see who they are as a person or in the case of extraordinary accomplishments what they have done as a person.
Believe it or not many people view the accomplishments within the technology field by accomplishment, not by race.
I so love this video BTW

My apologies, I created a new topic for this because I thought the message although triggered by the other post, was something positive to share amongst everyone.
Dr. Mark Dean Invented the PC
The first general-purpose digital electronic computer, one that could be programmed to perform a variety of calculational tasks, was the ENIAC (Electronic Numerical Integrator And Calculator).
It was designed and built in the Fall of 1945 by John Mauchly and J. Presber Eckert. ENIAC was originally built to calculate ballistic tables for the US military to aim their big guns. ENIAC was a monster of a machine, filling a large room and weighing 30 tons. It included 18,000 vacuum tubes and used 200 kilowatts of electrical power (the lights dimmed in its Philadelphia neighborhood when it was first turned on). ENIAC was the first general-purpose computer because it could be programmed (given different sets of instructions to follow) by the cumbersome procedure of reconnecting cables and flipping switches.
Later computers were much more flexible because they incorporated the idea of stored programs, conceived in 1945 by mathematician John Von Neumann (who worked on the Manhattan Project in Los Alamos). In this scheme, both the data being manipulated and the program of instructions for the computer are stored in memory. Modern computers use this same method.
Mauchly and Eckert later went on to work for the Univac division of Remmington Rand corporation. The Univac I (Universal Automatic Computer) was the first commercial computer, coming out in 1951. Most of these early mainframes were purchased (or rented) by government bureaus, the military, research labs (such as Los Alamos National Lab), large corporations, and universities. IBM (International Business Machines) entered the computer market in 1953 with its 701 computer. By 1960, IBM was the dominant force in the market of large mainframe computers. Smaller players in the mainframe market included Burroughs, Control Data, General Electric, Honeywell, NCR, RCA, and Univac.
Transistors and Integrated Circuits
ENIAC computer ENIAC computer Vacuum tubes consume lots of electrical power and are prone to burning out, which caused problems for early computers that used thousands of them. By 1960, the transistor replaced the vacuum tube as the electrical switching device in computers. The transistor (developed at Bell Labs by William Shockley and others in the 1950’s) is a solid-state semiconductor device typically made of silicon or germanium. It is much smaller, much more reliable, and consumes much less energy than a vacuum tube. A vacuum tube computer that previously filled a sizable portion of a room could be replaced by a transistorized computer system that filled a few cabinets. A good example of an early computer using transistors is the IBM 360, which dominated the mainframe computer market in the mid to late 1960’s.
The early 1960’s also saw the development of the microchip, or integrated circuit (IC), invented by Jack Kirby and Robert Noyce. An integrated circuit incorporates many transistors and other electrical components, all formed into a miniature circuit onto a single chip of silicon.
