I'm going to counter this with another anecdotal argument:

Today more people than ever are philosophers. How many people have influenced your thought while exploring the internet in past year (or 10 years)?

You do realize most of therapy is based on ideas from that millennium? Stoicism and Buddhism for example, among many others.

seeking insight from older philosophy is about starting a journey towards achieving contemporary philosophical insights.

One isn't supposed to conclude that these problems were or are ever solved.

Archetypical ideas are ancient and enduring because they're fundamental
