No disagreement, but these stories also make me worry for myself.

Tech moves so quickly, eventually I will fall behind. When I’m old, what scams will I fall victim to? What tech will confuse me and make me think it is sentient?

I know this guy was only 50, but I think of my grandfather in his 90s and getting old scares me because I just don’t know what I’ll fall victim to.

The optimistic prediction is that we eventually see a type of AI anti-virus but for scams and social engineering. Something that can filter incoming communications but also intervene in channels that are already open. There's probably good financial incentive to create a service like this since it would likely not only prevent outright fraud but could also help the user evaluate legitimate transactions so that they at least get an even break.

Exercising cognitive skills is, I believe, known to delay the onset of age-related cognitive decline, which is another excellent reason to avoid letting use of LLMs cause skill atrophy.
