Generally speaking, the longer something has been common the more time it will continue to be common. A fad vs a trend vs a tradition. Of course alcohol use can change. We see several cohorts with very low alcohol consumption. It's just that if we've been doing something for thousands of years, we're likely to continue to do it for thousands of years.
This is far from the first fluctuation of alcohol consumption rates we have data for. This is a major trend that will last decades but not a march to long term 0.
