Hicks said the extended flamenco passage at the end of "Gray Matter Mechanics" could be potentially jarring and felt that the album's science concept was "samey", but praised the band's musicianship and McShane's vocals, especially on album opener "Proponent for Sentience I – The Conception".

The reviewer also praised the song "Proponent for Sentience III – The Extermination" for feeling "like a natural conclusion, with its Grade A melodies and hair-raising moments.
