A lot of people in the Silicon Valley tech community and similar tech communities have historically been drawn to newer blockchains because their perception of technology involves rapid change and disruption. Thus many of them implicitly assume that older (eg. Bitcoin) is being and/or will be disrupted by newer.

In my experience, a good way to circumvent that is to remind them of communication protocols. Things like Internet Protocol, Ethernet, SMTP, USB, and others tend to have very long lifetimes once they reach dominance. That combo of simplicity and network effects lasts a long time and pushes most rapid change to the edges or higher layers, and that the underlying foundation moves more slowly.

That seems to effectively recategorize it in their perceptions with a decent success rate.
