is it possible to play music live with people online or is lag always too long?
as of now, this year (2022), using normal phone or chat software, the delay is much too long to play synchronized music together. there might be some specialized software/hardware solutions out there currently which i have not tried. but nonetheless, the latency will come down as the years progress. i'd estimate in 5 to 10 years the problem will be solved, unless the whole situation is upended by much more ridiculous problems
