Hype still sells and we still idolize people though. Businessmen such as Steve Jobs or (early) Elon Musk curate an image of themselves as a "genius", which leads to popularity of their products and influences trends and opinions in specific fields.
Really though, no single person did or invented anything alone. Every well-known and highly regarded scientist, inventor, or businessman built their work as a small increment on top of hundreds of predecessors. The Upright Thinkers by Leonard Mlodinow is a good pop-sci book that carries that point throughout.
I was interested in these "light" phones for a bit, but they seem a bit gimmicky and expensive. I understand not having a browser on purpose, but for communication, none of them (AFAIK) support Matrix or even XMPP (even some old feature phones had a Java Jabber client). Punkt MP02 supports Signal though.
Android phone with custom ROM (Lineage, /e/, Graphene, DivestOS...) is a possibility, and would be usable until hardware is incompatible with the phone/wifi networks.
If you have a patience of a saint, PinePhone and Librem5 are Linux phones, both in fairly early stages.
