An older analog is calculators. My college intro to stats course didn't allow them. We did simple arithmetic by hand and looked up things like roots and logs in tables. I still have my copy of this: https://www.amazon.com/dp/0849306922 I just tutored my nephew through his college intro to stats course. Not only are calculators allowed, but they had a course web app so that all they did was select a dataset, select co…
What the surface level take about calculators misses is that the average person can't do arithmetic in their head because they don't need to, but they also don't pull out a calculator in the many times a day it would be useful, like at the grocery store. People make horrible decisions with everyday home economics math and are taken advantage of. The lesson isn't that we survived calculators, it's that they did dull u…
Before calculators, i.e. slide rules, log tables, hand arithmetic: by the time engineers completed their university education most could approximate relevant parameters in their work to +/- 5% or the actual value. Slide rules would give you a result to 3 (rarely 4) significant decimals, but you needed to know the expected result to within half an order of magnitude.
After calculators, many graduate engineers will accept erroneous results from their calculations without noticing orders of magnitude discrepencies.
We constantly hear of spreadsheet errors making their way into critical projects.
With AI the risk is that even currently levels of critical thinking will be eroded.
