The fact that your father is able to navigate complexity doesn't really disprove my point. Some percentage of people will be excluded / unable to participate if things are decentralized. Whether that segment is sufficiently large, or whether people care about them having access, is left to each person's opinion. Centralization has significant advantages. People love one location for what they need because it simplifies things. That enables more folks to participate due to lower friction. Whether the downsides outweigh the positives is left to the reader. My broader point is the centralized/de-centralized discussion should be framed in terms of tradeoffs. One is not necessarily superior to the other; it depends on how each person weights the relative benefits and downsides. It's important to acknowledge that the general internet public, so far, seems to prefer the advantages of centralization. That may be because the disadvantages are hidden, or it may be a legitimate preference.
