At 300 baud, you’ll get a maximum download speed of 37.5 bytes per second. Your current 1Mbps connection gets you 125,000 bytes per second which is 3333 times faster! Good luck trying to load youtube videos on 300 baud. But anyways, this was an amazing piece of technology that paved way for what we’re using today. Simply amazing.
