It is in 'preview' and is still not ready for production use. Or is it? (It's really not)

'Docker Desktop on Apple M1 chip is still under development. We recommend that you do not use tech preview builds in production environments.'
and
'The kernel may panic...'
Sound very unstable for early adopters to use Docker on a daily basis to read these notes and disclaimers for this software on Apple Silicon. In a related note, not even the Android Emulator for ARM64 works fully on Apple Silicon. [1]
So despite all the hype and what the developers don't tell you, I'll pass and wait until the ecosystem is actually mature and out of 'preview' mode. By then the M1 Macs will be superseded by M2 Macs and above, which will be even more faster.
