By the time docker, virtualization, and programming environments are mostly sorted out, there will likely be a successor to the M1 on the market, so while I'm not GP, I do agree with the sentiment in this case. Especially with an ISA change.

I wouldn't expect official stable support to be available very soon. Even then, even if most of the official Docker image library will have ARM support, a ton of community images will need to be ported – all of this will take quite some time.
