The coming of conscious machines

Mankind has gone through three distinct turning points in its evolutionary history -- discovered fire 100,000 years ago; developed language 10,000 years ago, and invented wheel 5,000 years ago -- which triggered multitudes of other advances that have revolutionised human existence. Since then, within the overall arc of human history, not much seems to have changed. Else, we wouldn't be living like those who lived five millennia ago, with parents and pals, amidst cities, markets and governments. And, we wouldn't fear death, share gossip, build relationships and celebrate birthdays like those in the past. Isn't it a trivia that lot has changed without much remaining the same?
