People that use a keyboard spell out each word they type. They still need spellcheckers.

Why? Do you think signing is done by spelling out words?

Do you really assume that language does not change if there is no AI involved in teaching? Try reading texts from a century – or even 50 years – ago.

I am not an AI fan but your argument is just fearmongering.

I’m no specialist, but (1) don’t most solar panels have a fixed inclination and orientation? Depending on the location that will not be as optimal at each day of the year because of the tilt of the earth. (2) The weather/cliimate will have an effect too. Your 2nd image is apparently showing kWh/kWp - so the longer term yield (h=hours) divided by the theoreticall maximum (p=peak). So it shows longer term efficiency , vs the yield at a certain moment like you appear to be focusing on.

How was this handled in the age of typewriters?

How on earth did English typography get so weird with mdash, ndash, dash, hyphen, etcetera while most of the readers have no clue about the the differences. IMHO, just use dash.

Can you explain me how the different lengths of dash add to the understanding of the text, when I usually don’t even see the difference on my mobile phone screen?
