The phrase "how far we've come" is notably recognized as a song title by the American alternative rock band Matchbox Twenty. The song "How Far We've Come" was released in September 2007 as the lead single from their album "Exile on Mainstream." It reflects on human progress and significant historical events, illustrating the journey of society through a montage of moments in the music video. The song discusses progress and changes over time, metaphorically asking to consider how much has been achieved or transformed.

If the inquiry "how far we come" is looking for a general explanation, it is often used to reflect on progress, achievements, or growth from a starting point, whether individually, socially, or historically. Please clarify if the question refers to the song, a philosophical reflection on progress, or something else for a more tailored response.
