L'hégémonie numérique des USA, des GAFAs, ...
.cas des moteurs de recherche dominés par Google(US) et x(Chine), avec peu d'outsider et en difficulté à s'impose ou croitre: ex de Qwant (article/UD201812 +++, et les commentaires)
-Qwant revandique son indépendance des US, jusqu'à refuser d'installer ses serveur laba/y créer une société car cela supposerait de se oumettre au Patriot Act et au Freedom Act, donc obligé de donner des infos au gouvernement US s'il lui demande.
En pratique, Qwant reste néanmoins lié aux savoirs et capacités US:
-Qwant héberge ses serveurs dans un datacenter en banlieue nord de paris mais celui ci appartient à Equinix, société multinationale californienne, qui comme toute société Américaine est soumise au Patriot Act et au Freedom Act. Si les agences gouvernementales États-uniennes veulent surveiller Qwant, il leur suffit de s'adresser à Equinix et Qwant ne serait même pas au courant.
-Qwant, qui se developpe assez bien au Canada, semble y etre actif comme une ressource anglaise traduite en francais (indexe d'abord les page anglaises...)

Discovering the WolfranAlpha (WA below) search, it looks an enthusiastic concept & search tools. Rapid tries lead me to 3 rapid ideas/suggestions hoping this could help WA to broaden its knowledge database and wise-ness and updating:
1-WA should allow to give an url link (or more) and/or other information when a key word is not known by WolfranAlpha
Example1: "When and where was born Macron". At the opposite of nice answer for 'Mitterand', this fail because 'Macron' is not known by WA (or after deep search, as an animal). I would appreciate to be asked for help to document this word.
-entering text (ex: politician French man) and eventually click WolfranAlpha categories (
-entering on or more url of related web pages. ex https://en.wikipedia.org/wiki/Emmanuel_Macron
2-WA should allow to select or deselect found items in 'Assuming' section (and notably if several findings) and in data per input interpretation, notably hierarchy relationship (of "immunoglobulin A') may allow to refine the search for MW of Immunoglobulin M for example)
Example2: "What is the molecular weight of IgA". WA identifies 'molecular' but ignores 'weight'. With "What is the weight of IgA", WA identifies weight->mass ok, identifies Iga as a planet, and displays the general result '8330 Iga (1194 AO2) that may suggest the mass is 8300 while it is part or the planet name(?).
WA do not know the mass to this planet, nor that Iga can also be a bettle or a molecule.
-it would be nice that WA says "The mass (of the planet 8300 Iga) is not know in WA database – can you document it?"
-it would be nice that WA allow to deselect 1 or more Input interpretations ( 8300 Iga (1994 AO2) | mass ), allow to enter a other: I would like to help WE search eleswher, and/or learn that IgA is 'Immunoglobulin A'.
Searching 'Immunoglobulin A' is not know at it self, but related by WA to 'Immunoglobulin' (ok). However WA knows 'Immunogloblin A' (displayed in the hierarchy)! Again,
-it would be nice that WA allow to (de)select 1 or more items in the 'Hierachy datas (i.e. select Immunoglobulin A' and eventually others like 'Immunoglobulin E')
-Some other data may be useful to (de)select. I saw for exemple 'Constitutional parts'
2-WA should be able to link key words to reference web pages (for ex Wikipedia, even this is not always a reference!). For example the structural group 'Titin filament', displayed about Immunoglobulin, what unknown from me. Checking on Wikipedia, I understand that titin is a filamentous protein (not e globulin) that contains a modules with a immunoglobulin domain. Finally, I doubt that titin filament can be a correct structure for immunoglobulins! I point out this (putative) error just to show that WA should allow for inputs from visitors to detect problems, correct it eventually (or send information for WA updating),. I doubt that a search engine with only proper data sources may be attractive enough and survive in our fast evolving world.
