  • I’m an engineer. I use all of it. I use it whether I’m writing technically correct and accurate forensic reviews or doing math in my head (or on paper) to analyze a condition in real time or checking a complex finite element model to ensure that there are no improper assumptions or invalid boundary conditions. AI/ML is really useful for some things, and deadly for others.

    Rote memorization may seem unnecessary, but a mental catalog - whether it be quotes, body parts and systems, equations of natural phenomena, or even manufactured parts and specifications - is the hallmark of someone who can work independently in a real time industry. It may not matter for some jobs, but it’s make or break in others.



  • Yet. Infrastructure on this scale moves slowly and the transparentness of pricing changes on short time lines in physical stores is hard to track. It exists in emergency economies - we call it price gouging - but that’s usually quite obvious. The idea of dynamic pricing has existed forever - hotels, airline flights, movie tickets, taxi rides, even electric rates. As technology advances it offers the opportunity to use the technology to shorten the time window for pricing changes more and more. An extra two tenths of a percent profit seems like a trivial amount. Amazon and Walmart combined for more than a trillion dollars in sales last year. 0.2% is a very non-trivial $2 Billion. If it becomes available, it will be exploited.













  • To take a contrarian view, the plastics wins handily in the reduce scenario. The plastic required to make a bottle is somewhere around 1/25 of the material required compared to glass. It’s high tensile strength and fracture toughness means a huge reduction in material processed per container.

    The flip side to that is convenience - the ability carry and dispose of a 1/2 ounce plastic container, vs a pound of glass container - makes it ideal for conditions where you are less likely to recycle.



  • T-mos general coverage outside of city centers and interstates is trash (they’re all pretty bad, but Tmo is very binary). I’d get it over xfinity, but it’s not even offered in my major university town due to coverage limitations. And it’s not like there aren’t big pipes nearby - the university consumes more than 100TB of data traffic a day; their Netflix traffic alone was so large just 3 years ago that they were on the edge of getting a co-located Netflix rack on campus.
