I've even seen this with people who say they are interested in and following this tech. I don't get it. The same mistake just happens over and over.

Journalists are some of the worst offenders.

Yup, this happens for any technology with journalists. A noob journo will be absolutely clear that it's crucial they interviewed Jim Smith and not Jane Smith even if it so happens that gender was not at all important to the story, like maybe Smith witnessed a massive lightning bolt destroying the bandstand.

But they will muddle bits and bytes, nanograms and milligrams, volts and amps and they barely even seem to notice that they did it.

Sometimes they insist on being incorrect.

The Guardian refuses to write the degree symbol for temperatures, for example, and have even put this error into their style guide.

I don't want a degree symbol on my temperatures, but that's because I want them in Kelvin so they shouldn't have one.

300K is too hot and I begin sweating. The Grauniad's House Style is the least of its problems.
