you can choose to see it as empty/hollow/vacuous if you want but i would disagree

yes all of human history is 'somewhere' on the spectrum/continuum , but for the vast majority of our known history technological progress was relatively slow ; for generations your life and your childrens lives would be much the same as your great-grandparents lives were , varying relatively little over hundreds or thousands of years

that is not the case anymore

call it around the widespread use of electricity or even a little before , but personally i think electricification is/was the first big step and then the computer was the 2nd , maybe the internet can be the third and 'social-media' platforms like reddit/youtube/etc are one of the most recent large-scale transformers ; obvs bitcoin/cryptocurrency and AI deserve their own recognition as well

bottom line tho , yes things have always been changing , the only constant is change , but more recently [ie the last century or so] , our rate of change has increased significantly

this is what an exponential curve looks like , slow and shallow at first and then getting steeper and steeper over time

the 'singularity' is not necessarily any specific point along the curve , it is moreso in reference to when the curve gets so steep as you are getting so far away from your previously understood worldview that it seems like night/day differences [ie horses vs automobiles , computers vs manual , AI vs humans , electricity vs woodfires , antibiotics vs none , etc]
