This is about weather forecasting, which is still hard because of the lack of small-scale data, which leads to the introduction of small initial errors, which multiply in chaotic systems to become big errors. This is how chaos works. When you hear that scientists are getting better at "controlling chaos", you know we're in for some sh*t:
New theoretical framework unlocks mysteries of synchronization in turbulent dynamics
Jan 2024, phys.org
Japan - "By considering this turbulence phenomenon as 'synchronization of a small vortex by a large vortex' and by mathematically attributing it to the 'stability problem of synchronized manifolds,' we have succeeded in explaining this critical scale theoretically for the first time," explains Dr. Inubushi.

We keep making the same mistakes with spreadsheets, despite bad consequences
Jan 2024, Ars Technica
Industry studies [from 1998!] show that 90 percent of spreadsheets containing more than 150 rows have at least one major mistake:In general, errors seem to occur in a few percent of all cells, meaning that for large spreadsheets, the issue is how many errors there are, not whether an error exists. These error rates, although troubling, are in line with error rates in programming and other human cognitive domains. In programming, we have learned to follow strict development disciplines to eliminate most errors. Surveys of spreadsheet developers indicate that spreadsheet creation, in contrast, is informal, and that few organizations have comprehensive policies for spreadsheet development.
