These so called leaps are attributed to something called the "technological singularity." Essentially, it means that as technology progresses, it enables further advancements at a quicker rate. Each technological breakthrough serves as a foundation for new developments, leading to a compounding effect where progress accelerates due to the tools, knowledge, and capabilities provided by existing technologies.

Due to advancements in microscopics, super cooling and information sharing Heike Kamerlingh Onnes discovered superconductivity when he observed mercury's electrical resistance drop to zero at temperatures near absolute zero.

There are people wayyyy smarter and with access to wayyy more resources than the ordinaries like you and I that are the single reason for these leaps.
