> It is generally accepted that Newton developed the concept of calculus in the mid-1660s. He wrote a few separate papers on it in 1669, 1671 and 1676 but didn’t publish any of them at the time – they were only published much later, in the eighteenth century.

> Meantime Leibniz is also believed to have independently invented calculus in the mid-1670s. He claimed to have developed the ideas around 1674, publishing them ten years later in 1684.

I feel like that's how science works. You build and build and build, and at one point, what others built can be used as a platform for new builders and that's when we perceive these quick jumps in technologies.
