Excellent summary.  Solid also provides access control, so it respects a
user's privacy.

It strikes me that access control is perhaps the next thing to be delivered
in the evolution of the web.

For example search engines crawl public_html, index it, and allow it to be
searchable.  It's easy to think, this is the whole web.  However sites like
facebook allow an access controlled experience, shared with your roster of
friends.  Solid takes this concept to a new level.

The web that public search engines cant see or track is often called the
'dark web' but actually it's just the web that respects people's privacy.
A new web that is controlled by its users poses threats and opportunities
current model.  There is a current narrative of 'dark web' and 'light? web'
-- a better new narrative would perhaps be the 'public web' / 'shared web'
/ 'personal web'.

The other aspect of solid is realtime updates to provide tight feedback
loops.
