YSK: if you live in the US and your state's drivers license doesn't meet certain security criteria, you will need to travel with a passport starting Jan 22nd

A lot of states have been granted extensions until later in the 2018 calendar year, and some states are already compliant. You should check online on the status of your state's ID, so you don't run into any travel issues starting this January. It looks like New York's extension is still under review, which would mean January 22nd is the day that residents with a NY drivers license will need to travel with a passport or other valid forms of ID (unless the extension is granted before that).

Note: this is only relevant to US residents who travel domestically and use their state's drivers license as their form of ID.

TL;DR - check the DHS website above. Apply for passport if your state's drivers license doesn't meet criteria for traveling domestically in US.
