You're assuming the only form is the last kind. As a human, I most prefer the electric cycle but I expect most will tend towards some kind of car. For the foreseeable future, only cars and cycles will exist because we don't yet know how to achieve deep understanding.
The algorithms understand in the sense of a set of rules to follow, transforming inputs to desired outputs. The rulebook doesn't merely consist of a look up table of all sentence pairs therefore at least some kind of understanding must be present. The algorithms can't turn words into stories with actors and predictions about their internal state, so I agree the understanding is shallow and far from human like.
Humans can often, even if not all choose to, step outside the system by integrating various modalities, propagating errors, to realize they're being forced to learn garbage. The machines can't reason outside the system. Compare with an animal of pure instinct (which are less common than many have supposed) whose behavior displays an implicit understanding of its environment's statistics.
DeepL translate: Das heißt: wenn zwischen Sprache A und Sprache B unbedingt etwas übersetzt werden muss, wird 2017 ein Zweisprachiger den Boden _absolut mit maschineller Übersetzung wischen.
At first I accidentally left in the underscore with Bing Translate I got:
Zum Witz: Wenn etwas absolut übersetzt werden muss zwischen Sprache a und Sprache B, in 2017 wird eine zweisprachige Person noch _absolutely MOP die floor_ mit der maschinellen Übersetzung.
Removing them, Bing Translate: Zum Witz: Wenn etwas absolut übersetzt werden muss zwischen Sprache a und Sprache B, in 2017 eine zweisprachige Person wird immer noch absolut wischen den Fußboden mit der maschinellen Übersetzung.
I don't speak German but mixing and matching between the three, I'm guessing the ranking for this example is Bing, DeepL, Google.
