The Tech That Will Invade Our Lives in 2020

Tech is in our homes with thermostats that heat up our residences before we walk through the door. It’s in our cars with safety features that warn us about vehicles in adjacent lanes. It’s on our television sets, where many of us are streaming shows and movies through apps. We even wear it on ourselves in the form of wristwatches that monitor our health.

In 2020 and the coming decade, these trends are likely to gather momentum. They will also be on display next week at CES, an enormous consumer electronics trade show in Las Vegas that typically serves as a window into the year’s hottest tech developments.

At the show, next-generation cellular technology known as 5G, which delivers data at mind-boggling speeds, is expected to take center stage as one of the most important topics. We are also likely to see the evolution of smart homes, with internet-connected appliances such as refrigerators, televisions and vacuum cleaners working more seamlessly together — and with less human interaction required.

Then in December, Amazon, Apple and Google came to what appeared to be a truce: They announced that they were working together on a standard to help make smart home products compatible with another.

Yet the rollout of 5G was anticlimactic and uneven. Across the United States, carriers deployed 5G in just a few dozen cities. And only a handful of new smartphones last year worked with the new cellular technology.If some of this sounds the same as last year, it is — but that’s because new technologies often take time to mature.

Here’s what to watch in tech this year.
