P\u00ebr k\u00ebt\u00eb arsye, disa vjet m\u00eb par\u00eb, t\u00eb gjitha portalet globale t\u00eb pun\u00ebs u mbush\u00ebn me oferta p\u00ebr Data Scientists, pasi t\u00eb gjith\u00eb ishin t\u00eb bindur se duke marr\u00eb nj\u00eb specialist t\u00eb till\u00eb n\u00eb ekip, mund t\u00eb nd\u00ebrtohej nj\u00eb supermodel m\u00ebsimi t\u00eb makineris\u00eb, t\u00eb parashikohej e ardhmja dhe t\u00eb b\u00ebhej nj\u00eb \"k\u00ebrcim kuantik\" p\u00ebr kompanin\u00eb.
