This is a British thing called self-deprecating humour where he's already thought ahead to those who will critically ask, "wouldn't it be less effort to just open the Weather app every morning!?" and is jokingly acknowledging that yes, it would be, while signalling to other hackers this shared feeling we all know that we don't do these things to save time even if we say we do, we do them because they make us happy.

I also wrote a script that downloads my mum’s favorite series from public broadcasters, puts them in Plex and sends her a text message. Is it necessary? No, but it was fun.
