It will, which is why I write until I'm figuratively blue in the face on here about how overpowered the 3 point shot is. There's really no counter to it. It's too statistically effective and too hard to defend. Sure, we'll get some occasional post-play and midrange shots when the situation warrants it, but the game will be dominated by 3s, even when they're not taken, since the spacing created by defending the 3 is what opens up the lane for the next most effective shot in the game: layups/dunks.
Charting the trend, the league took an average of 29 threes last season. This season, it rose to 32 per game. 10 percent increase in a season. No signs of it slowing down. As Harlem said, more and more teams will model themselves after the Rockets since it's the best way to maximize value when you don't have two or three superstar level players on the same team. Curry is the most influential player (in terms of playstyle) of the past decade, maybe since Jordan, meaning kids all over the country are emulating him, translating into more chuckers entering the game in the coming years.
I honestly think casuals love it. The NBA completely dominates social media, which is casual grand central station.
