Ask HN: Has Flash Been Replaced?

Adobe plans to end support for flash in 2020 . Chromium plans to remove it by then. Yet, i am noticing many websites still use flash, because surprisingly it works better than alternatives that were supposed to work better. I have seen it being mixed with webrtc for video and some other uses in various places. It is also odd that 10 years after people declared the end of it there are uses for it where there are no decent alternatives. E.g. I was also looking for a replacement to standard Flash-based website chat room, and there aren't any. So, is flash really ready to be removed from the web?
