100Mbps UP will never happen because large uploads are considered undesirable. Providers want us to consume not produce content.
So we have more use cases than ever before that benefit from symmetric speeds.

In the past 5 years the amount of video and streaming (pre-recorded and live) has exploded. And remote/WFH culture is advancing. It's time for US internet providers to catch up.
