“Imagine a widely used and expensive
prescription drug that claimed to make us
beautiful but didn’t. Instead the drug had
frequent, serious side effects: making us
stupid, degrading the quality and credibility of
our communication, turning us into bores,
wasting our colleagues’ time. The side
effects, and the resulting unsatisfactory cost/
benefit ratio, would rightly lead to a
worldwide product recall.”

Perhaps the available font cannot show exponents. Shakiness in units of measurement provokes concern. Slides that use hierarchical bullet-outlines here do not handle statistical data and scientific notation gracefully. If PowerPoint is a corporate-mandated format for all engineering reports, then some competent scientific typography (rather than the PP market-pitch style) is essential. In this slide, the typography is so choppy and clunky that it impedes understanding. The analysis by Dr. Edward Tufte of the slide from the Debris Assessment Team briefing.
