You'll see a lot of "best of" lists around this time of year. But "best" is a limited word. What if the ideas and people that dominated weren't, in fact, very good? Conversely, what happens when the products or concepts that showed the most promise didn't ultimately prevail? As Engadget looks back on the year that was, we prefer to think of the world using a different binary: winners and losers. In 2018 the headphone jack basically became extinct on smartphones even as many people were still using it. Huawei is making great phones, even though its devices are nearly impossible to obtain in the US. Cryptocurrency made headlines, but not always for the right reasons.
