Still so crazy that our field is so young that people like this are only now passing away.

Indeed. When I was a young CPU designer (working on walk-in, refrigerated, mainframes implemented in 100K-series ECL) several of the old bulls I worked with had been CPU designers in the days of vacuum tubes. I loved hearing the stories of the early days, and considered it a privilege to learn the craft from them.
Einstein was still alive when my mom was a teenager.
To be fair, 94 is quite an old age.
99.9% of tech was developed within about the last 3-4 generations, no?

Maybe arguably not true for scientific progress.

Modern technology is mainly the result of chemistry and materials sciences. Key events are the discovery of nitrocellulose in the 1840s and the introduction of the Bessemer process of steelmaking in the 1850s.

Nitrocellulose starts the development of guncotton, high explosives, celluloid, photographic film, and all sorts of modern plastics. Cheap steel enables engines, steel hulled ships, ICE vehicles, chemical plants, oil refineries, electrical machinery, etc.

Further progress in chemical engineering results in fuels, pesticides, fertilizers, pharmaceuticals, solid state devices, integrated circuits, lasers, etc.

Well I mean, yea... Modern tech is the result of scientific progress...
Depends on what you define as "tech", no?
Indeed: ships, metallurgy, chemistry...they had lengthy births.
Chemistry is a science. Chemical engineering is the application of that science (to create technologies).
Chemical engineering is mostly about 'plumbing' - pipes, tanks, valves, etc. Fluid dynamics. It's much closer to physics than chemistry most of the time from what I understand.

Chemistry doesn't have the same stereotypical relationship to engineering that physics does.

(This comment is based on what these terms mean in the UK at an undergraduate degree level. I'm an electronics engineer and I know a couple people who studied chemical engineering. If the terms mean something different elsewhere in the world I'd love to know :) )

If you saw how an industrial chemist works you’d see it more akin to engineering than science.
By value add, I mean. But I don't know what's ambiguous about what is and isn't tech?
tech is anything made, invented, not natural. So, the stirrup, eyeglasses, agriculture, our control of fire.
Yea. Anyways, what's so controversial about my comment you responded to?
That's a case that might be argued, though pinning down both what technology is and quantifying "innovations" (or inovation) is ... notoriously prickly.

My working definition borrows from John Stuart Mill, who identifies technology as the study of means (to an end or goal), while science is the study of causes (how or why things happen, to which I'd add a general notion of "structured knowledge").

There are other forms of knowledge, an interesting topic itself, but I'll skip that.

There's a tremendous set of ancient technologies, which can get expansive depending on your views. Everything from speech to simple machines, textiles, agriculture, medicine, metalurgy and mining, and ancient chemistry and alchemy.

What changed starting, arguably, at some point between roughly 1620 (publication year of Francis Bacon's Novum Organum) and about 1800 (patent expiry on James Watt's enhancements to the Newcomen steam engine) was a change in attitudes to both science and technology (or the practical arts, as they were then called), due to numerous factors. Much of that owed to the availability of better and more abundant (at least in the short term) fuels: coal, oil, and natural gas, and the capabilities afforded by those, especially in metallurgy (greater strength, purity, specifically-tuned characteristics, and of course, abundance), as well as in the understanding of natural phenomena: optics, thermodynamics, elements, electricity, and later radioactivity, affording more capabilities.

There was still a huge amount of pre-industrial, non-industrial technology, much of it originating in China and documented spectacularly in Joseph Needham's Science and Civilisation in China, a 30+ volume opus begun in the 1950s and still in development.

Many studies of technology look at patent filings, which is at best a rather poor metric -- one that's in many ways a bureaucratic, commercial, and ontological artefact. Looking at the costs and derived value might be of more use. I've been looking into an ontology of technological mechanisms, for which I've generally settled on about nine factors (discussed in other comments on HN, as well as elsewhere) which I've found useful.

Much of what is commonly called "technology" today falls into only a very narrow region of that. And much of what is considered economic growth can be traced very specifically to the increased energy available per capita in productive use.

There's also a pronounced set of diminishing returns to increased innovation and R&D, generally. Suggesting an other-than-bottomless reservoir of potential from which to draw.
