The first uses of iron alloys such as steel dates to around 1400 B.C.E. Other technological advances made during the Paleolithic era were clothing and shelter; the adoption of both technologies cannot be dated exactly, but they were a key to humanity’s progress. As the Paleolithic era progressed, dwellings became more sophisticated and more elaborate; as early as 380,000 B.C.E., humans were constructing temporary wood huts. Clothing, adapted from the fur and hides of hunted animals, helped humanity expand into colder regions; humans began to migrate out of Africa by 200,000 B.C.E. and into other continents, …

Past automation has both substituted and complemented labor; machines replaced humans at some lower-paying jobs , but this was compensated by the creation of new, higher-paying jobs. Studies have found that computers did not create significant net technological unemployment. Due to artificial intelligence being far more capable than computers, and still being in its infancy, it is not known whether it will follow the same trend; the question has been debated at length among economists and policymakers.

Genetic engineering will allow far greater control over human biological nature through a process called directed evolution.
