I also think ageism is dumb, however the age - 25 - that he mentioned isn't an arbitrary cut off point.
There have been studies, such as by the National Institutes of Health that show that "the part of the brain that restrains risky behavior, including reckless driving, and thinking skills is not fully developed until the age of 25." Meaning the Frontal Lobe and Prefrontal cortex have not yet matured until 25, that's the area of the brain area responsible for planning, prioritizing and controlling impulses.
So does this have much to do with calling people "hipster" in a disparaging way? And why "hipster", but seemingly not other insults (which >25 year olds certainly still make)?
He's just yelling at kids to get off his lawn and lacks the self-awareness to pay attention to who's lawn he is standing on while he does it. There aren't any deep truths hidden in his comment.
Not his either? Before he yells at others to get off it, he should get off it himself.
He is making a baseless judgement about an entire age group because he thinks that age group makes baseless judgments. The lack of self awareness is ludicrous.
I would believe it's more to do with the degree to which a person's identity is externalised. As soon as someone doesn't have the same taste in music, clothes, lifestyle - then it is an attack on them personally. I don't think it necessarily lessens with age rather shifts to other things like postcode envy.

There is an amount of truth in this.
