Is the singularity coming though? Exponential curves have a way of stopping. This can be s-shaped where it ends at a new level, or it can crash, or other fun shapes. In the real world things don’t go to infinity… except for actual singularities (mostly black holes).

Moore’s law has basically ended, for example. Chips aren’t doubling the number of transistors every 2 years anymore (since 2010 or so). Cell phones have stopped evolving recently, and are basically all identical now.

My grandmother was around when the first car arrived in her county, when the Wright Brothers first flew, when radio and television arrived, through commercial flight, when the first satellite orbited the earth and when humans first walked on the moon. She got a phone and the Internet, lived through the discovery of the shape of the DNA molecule and vaccines that wiped out smallpox.

In the USA the y changed from having the KKK being a powerful party to having civil rights laws and banning Jim Crow laws, through the roaring 20s and the great Depression, and through the New Deal and Reagan’s dismantling of the guardrails that kept capitalism surviving without killing the host.

I’d say the changes of the 21st century so far - while noteworthy and important - are not faster than the changes of the 20th century.

To be honest, I think the changes of the 19th century were even more massive. The step function of work being limited to what humans or animals could do to machines altered our society and our relationship to the world in ways unequalled since agricultural societies evolved. Railroads, telegraphs, electricity, steam ships. We discovered germ theory and electromagnetism and evolution. Amazing.
