since the 1990s, we have seen a plethora of computer technologies contribute to this and now very little on the internet or in media can be trusted and this is BEFORE AI:
Photoshop has been perhaps the most abused technology for warping shapes of women and overly “cleansing” skin tones and imperfections
Autotune technologies “corrects” musical pitch in real time for most live performances
Pitching correcting software is used by music produces to snap vocals to the exact pitch - even though this may not be the pitch stringed instruments are playing
Youtube musician influencers take this a step further by not only applying pitch correction, additional vocal audio effects, but produce their videos of themselves miming to to this and decieving viewers that they are achieving all this in “zero-shot” live performances
