One interesting thing: when you look at the “best” colleges for specific subjects say 80 years ago it seems like there was more heterogeneity and small colleges with some specialty. Today the best colleges are all “the best” at every subject.
Funny, growing up in the US we’re tsight a version of human history that centralizes technology. We’re taught that what makes Australopithecus special was walking and inventing stone tools, homo erectus is inventing fire, and so on. Invention is almost framed as what makes us human!
Good point, though I don't find looking at a selection of areas as too convincing. I could just as easily choose areas with consistent exponential growth that I would guess don't look like this, like solar panels or genome sequencing. Even if things were getting better on average you would expect some things to get less efficient over time too. (for example, think about that inflation components chart people share all the time)
One last thing: we would probably want to look at output and not inputs. Robert Gordon's sort-of nemesis, Chad Syverson, has done w... (read more)
One thing I'd like to see is a discussion of the potential for measurement error. For example, software is notably deflationary yet we don't see that in the statistics due to how we count. (We still don't really know how to value the contribution of software to GDP.) Bloom (2020) may just be measuring the wrong outputs for the current type of progress. For example, if publications or patents are a weaker signal for ideas than in the past, the methodology breaks down.
I know it but it’s still pretty specific to the technologies and products the author is interested in. I’m more interested in a general question of: there are a number of technologies where the implementation barriers seem nontechnical, and it seems like it’s getting worse. Curious why.
The premise isn't exactly right here. There are venture backed companies that primarily develop and license IP, like Qualcomm, ARM, and RAMBUS. Plus, like, the entire biopharma industry. Sometimes companies make spinoffs that just hold IP for joint ventures with other companies. So this does happen; there just needs to be infrastructure to use the IP, like people to manage the licensing process and a corporation to actually hold the IP, since it always needs to be assigned to someone (IP cannot legally exist in the ether). Investors do also sometimes take ... (read more)
