Phb page 37, on selecting languages, says:

Your character knows at least three languages: Common plus two languages you roll or choose from the Standard Languages table. Knowledge of a language means your character can communicate in it, read it, and write it. Your class and other features might also give you languages.

So your character gets at least three languages and also—so, additionally—what you get from other features like class or background.

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.
