In the Brussels bubble, “digitalisation” is the buzzword du jour. I always thought it meant scanning printed texts and converting them to a digital format. That’s apparently now “digitisation” (and the distinction between the two is still not entirely clear to me).
I gather that “digitalisation” refers, in EU policy circles, to the growing adoption and spread of digital technologies across the whole of society (and the economy in particular). I’ve seen it compared to the process of electrification.
