There is a recency bias. But there's also an absolutely undeniable acceleration in physical and other quantifiable bases (knowledge, understanding, population, global impacts, energy utilisation, raw materials consumption, pollution) through time. For Earth, the very rapid emergence of life (within the first few hundred million years), and then the lack of extensive complexity emerging for another 3 billion years , u…
When I read about the history of science I get the impression that almost everything of interest happened between about 1860 and about 1960. Since then there has been continuous quantitive progress in some areas, such as "Moore's Law", but qualitatively nothing to compare with what happened in the period 1860-1960. It's subjective, of course. Maybe I'm just old and nostalgic.
Vaclav Smil (already mentioned several times in this thread) points to the half-century from 1875--1925 as the peak of invention, and more specifically, the decade of the 1880s. This was the time when discoveries based on electricity, coal-tar chemistry, petroleum, some bits of genetics, and others were coming into the fore. There are very few modern inventions which cannot be traced to this period. (Radio, TV, lasers, microwaves, and genetic engineering are the main exceptions). I see this as a landmark breakthrough in both knowledge and means, the latter largely supplied through the vast untapped energy of fossil fuels.
(Aknowledging their impact and declaring them an unqualified good are two entirely different matters. Yes, they changed our world and made modernity possible. Yes, they will destory that as well if we keep using them, and even if we want to, they will ultimately be exhausted.)
There are a few laws of progress. Moore's refers specifically to network and size effects, and has some foundation in business practices and goals (that is, what we see as "Moore's law" phenomenon is in part driven by the performance and product targets and timelines of firms in the sector). There's also Wright's Law, which refers to the level of improvement seen with additional experience. If memory serves, about a 20% efficiency gain with each doubling of output. (This was noted especially in the US with military output during WWII, especially in the rate of aircraft and ship manufacture.)
There are also scaling laws which refer to the reduction of defects, increases in precision or accuracy, and reduction of downtime. Here, each additional "nine" of performance tends to cost 10x the previous --- a case of rapidly diminishing returns.
On the progress of science, I've only looked into this casually and haven't found a good or suitable measure (itself a fairly deep question --- typical metrics such as patents filed have ... ginormous fucking issues, as a term of art...). But looking at Nobel Prize awards in Physics, Chemistry, and Medicine, what we tend to see is highly foundational discoveries prior to about 1960, and remarkably less so afterwards. In all three cases, I also note a strong presence of detection and measurement discoveries in the post-1960 era, which is to say, discoveries that increase our ability to detect various phenomena, as in remote astronomical measurements, chemical detection, or looking at body or cellular processes. Physics seems especially notable, with the pre-1960 period seeing numerous particles, forces, and principles (quantum mechanics, relativistic effects (but not the Theory of Relativity itself), and basic phenomena such as radiation).
I've got thoughts on that, you might try looking up my past threads on "ontology of technology" --- these are informational mechanisms.
