I recall @pg &#x27;s essay immediately:<p>&quot;WHAT YOU&#x27;LL WISH YOU&#x27;D KNOWN&quot;<p><a href="http:&#x2F;&#x2F;www.paulgraham.com&#x2F;hs.html" rel="nofollow">http:&#x2F;&#x2F;www.paulgraham.com&#x2F;hs.html</a><p>here is what he wrote: If I were back in high school and someone asked about my plans, I&#x27;d say that my first priority was to learn what the options were.<p>Silicon Valley, or people on HN generally, are doing this unconsciously. I was shock that a lot of (non tech)people accept things as they are (as default). They let phone APP like LinkedIn scan and grab the contact list; buy things that are in the trend; over estimate price but underestimate value, etc.<p>ADs is good only if they introduce something new, CES-ish new, something that are not in the trend but available up on request. Something that you are not aware of, hope we get to that type of ad-era soon enough.
