I don't disagree with you, but I would clarify that it's not $120k of tokens, it's $5k of Claude subscriptions. And also I suspect he would consider "affordable" to be "as a well paid software engineer". So I guess his benchmark is really more like: does $5k of subscriptions reduce to ~$500 next year.
I don't think it will. I also don't think this is really that affordable, but I'd imagine he'd call it accurate.
