For the few times that I have tracked myself doing various activities, I have found that I didn't even need to do anything with the data, I was actively changing habits whilst I knew I was being monitored. For example, I wore a GCM for a few weeks and I found it difficult to live my "normal" day to day lifestyle. I wanted to do the things I felt were "right" and "healthy". Whether or not that is a good thing or not is a different topic, but just my 2c.

I think a broad tax would just make it more difficult for middle and lower class to fly. Tax the business/first class and frequent flier, but don't push people who can already barely afford to fly out.

This is likely because the blog is AI generated and keys off this point from Karpathy: "As a preview, by the end of the script our model will generate (“hallucinate”!) new, plausible-sounding names.", so the LLM just repackaged that into something that is obviously wrong, which is kind of ironic.

Its interesting to me that over the last 10 years of working in agile teams, not one team has analyzed burn rates to see if we are doing better/worse over time. Its like every sprint is a clean slate and no one actually gets better at their job...

Its partly this, but hardly any developers I know were writing code for 8 hours a day. 4 on a good day and the rest was meetings or other auxiliary activities. From what I have gathered, companies have no idea how to measure the productivity gains yet.
