The invention of the cotton gin in 1793 significantly increased the necessity of slavery in the United States. This machine revolutionized cotton processing, making it much faster and more efficient, which in turn heightened the demand for slave labor to cultivate and harvest cotton. While computers and electric light bulbs are impactful inventions, they did not directly influence the expansion of slavery like the cotton gin did.
It is generally considered that great inventions made possible by science and technology include such things as the electric light bulb, the steam engine, the internal combustion engine, the electric generator, the telephone, the television, the computer, and the nuclear bomb.
