In a totally different context came across the old Pulitzer Prize winner "The Soul of a New Machine" (when straplines for book titles were not in vogue!) by Tracy Kidder that came out in 1981. Though I have heard of it, never picked it up, though it was considered a classic in computer science world. Decided to order a copy. Since I read these two books back-to-back, my usual triggers, comparing the authors' writing style, their background and how the material was presented were all swirling around in my mind.
Just for fun, I first asked ChatGPT to write a book review in my style for the Soul of the machine book. I could do that by pointing it to my blogsite that has archives of my previous reviews so that it can learn. Here is the exact prompt I gave, and the review it wrote. This is to see how close its writeup is compared to how I felt.
My prompt to ChatGPT: Write a book review for "The soul of a new machine" by Tracy Kidder in the style of Sundar Vedantham using book reviews posted at https://sundarvedantham.blogspot.com
Here is what it came up with:
I was expecting it to write a review exactly like what I'd have written (i.e. if I copy/paste and send it out as my review, no one will know the difference). But it interpreted the prompt to mean that it should mimic someone else writing the review, referring to my style (hence the "as Vedantham would ask" lines). While it did manage to write prose that is similar to how I may write, actual takeaways were quite the opposite to what I felt reading the book! I have read couple of other books in the past, with major expectations that turned out to be duds for me. Along those lines, despite this one being a Pulitzer Prize winner, I didn't find it very engaging. Being a 4 decade old book, perhaps it hasn't aged well. It is written by the author Tracy Kidder who is a writer (i.e. not computer scientist). He was invited to hang around the design team of a computer company called Data General, as they were designing a new Mini-Computer (similar to DEC's PDP-11) called Eclipse.
Data General was a badass computer company in the 70's. It was known for aggressive sales techniques, bold advertisements (look up "They Say IBM’s Entry Into Minicomputers Will Legitimize The Market. The Bastards Say, Welcome." advertisement that never actually went out) and so forth. While the DG's efforts & style were unique and heroic compared to IBM type companies at that time, to me Kidder kept sounding like a total outsider (perhaps because I am an insider) who was trying to sound like an insider, explaining geeky technical details of computer design in not so easy to understand prose for common audience. Author who is not a techie trying to sound like he is very tightly integrated as part of the tech team, describing how he was in the lab, went fishing with the tech leads, ate dinner with them, describing everything in first person singular (I did this, I asked him, my wife said) sounded odd. Reminded me of Carly Fiorina, when she became CEO of HP, putting up her picture next to Hewlett & Packard in their corporate office. It made HP engineers giggle since they didn't see her as an equivalent techie that deserved to have her portrait next to the founders, both of whom had passed away! Kidder certainly didn't go that far. But more of an observer style reporting in third person might have come across better. Perhaps it is just me. If you have read it and consider it a classic, educate me as to what I am missing and what impressed you so much. 
OTOH, Kraus is a Prof. at Northwestern University, running a lab called Brainvolts for decades, guided about 30 PhD students and has written just this one book that captures her lifelong work spanning decades. While this profile matches that of some very good books I have read in the past, I found Kraus' prose unnecessarily technical for a mass audience book. Here is an example, "Their hearing threshold did not change, but the way the auditory cortex responded to sound changed, reflecting a disorganized tonotopic pitch-processing mechanism". Takes a while to get used to her discussing the differences between afferent (moving upstream from ear towards brain) and efferent (moving downstream) in such language elaborately. I often complain that books usually contain walls and walls of text but instead should sprinkle around many more figures & pictures to help illustrate the discussion. While I was delighted to see Kraus using a lot of pictures, I found many pictures that didn't add much value. They felt so unnecessary, perhaps only helping to increase page count nudging it towards the 300-page mark, which is typical for books of this kind (this one is only 267 pages long). In addition, there were several pictures reused with permission from somewhere else. Probably the originals were color pictures that were meant to be seen in larger format. Rendered in B&W, small format portrayal in this book, things written inside those images by hand were hard to read and so again were annoying.
But once we get past those annoyances, this book nicely covers the importance of good auditory capacity we should strive to retain for our mental health. Kraus writes in first person, talking often about her family, children, husband, mother, and students. In this case, since it is all her research, it does sound appropriate, at least to my ears. She covers the subject from multiple angles, the ear-brain functionality that enables us to hear & comprehend sound, bird songs, poverty are just few angles she takes up. Often when you dig into any specific areas of research, you unearth very interesting facts and nuances that are not intuitive. Kraus does a lot of research by measuring midbrain electrical signals that can be measured from our scalp (FFR - Frequency Following Response), that she uses as a point of departure to study the effects of sound on autism, aging, and so on. Here are some such findings Kraus talks about:
- Both musicians and athletes are better at hearing & understanding speech under noisy conditions. But the brains of the musicians amplify the signal (i.e. speech) to understand what is being said better, while athletes suppress the noise to reach the same level of understanding.
- Plants are able to "hear" or are sensitive to sound. Her team demonstrates it using a pot that has two diverging legs at the bottom. Since plants grow their roots towards the area where water is found, without really providing water, but by creating the sound of water, they are able to observe the root growing towards that leg of the pot!
- Marine lives thrive near coral reefs that have a lot of activity reflected by the level of sound. By playing marine sounds through speakers near dead coral, we are able to attract more fish and other marine beings to settle down in that area, helping the area revive!
- Being a practicing bilingual and performing music of any kind are two areas that really help.
- I have attached a 7 min long radio interview she gave. Near minute 6:30 see how by measuring the electric signals on the scalp as our brain listens to a piece of audio (few seconds of music, in this case) we can even recreate the audio back.
I went for an audiology exam recently. The plot below shows my left/right (blue/red respectively) hearing thresholds. This is typical age-related hearing deterioration at different frequencies.
I did do well on speech audiometry, word recognition tympanometry, and other such tests. Bur from previous test results completed couple of years ago, I can see a 5db drop in most frequencies. Kraus points out how if we see bleary road signs, we won't blame the highway department for installing fuzzy signs but get our eyes checked but when we don't hear well, we blame the noise around us and don't rush to get our ears tested! As we lose hearing slowly, as almost all of us will as we age, conversations become difficult. We slowly become apprehensive and hesitant about annoying others by asking them to repeat what they said. We then start to avoid interactions and tend to become more and more isolated leading to depression. We may also see this behavior in our own family elders. Simple fixes are getting tested by an audiologist to track any deterioration over time, learning a new language, playing music, avoiding excessive noise that can damage our ears, getting the right kind of hearing aids, and so on. I am planning to put these ideas into practice in my life. Do check out the Brainvolts lab website that has interesting short videos, papers, tests. If you won't pick up this book, you can search for her name online and listen to interviews/talks.
