I don't see why they would care that they are destroying sales of the intel MBP 13. Let consumers buy what they want - the M1 chip is likely far higher profit margins than the intel variant, and encouraging consumers to the Apple chip model is definitely a profit driver.
Some people especially developers may be skeptical of leaving x86 at this stage. I think the smart ones would just delay a laptop purchase until ARM is proven with docker and other developer workflows.
Another consideration - companies buying Apple machines will likely stay on Intel for a longer time, as supporting both Intel and ARM from an enterprise IT perspective just sounds like a PITA.
That uses hardware virtualization which is very much dependent on the architecture. Running an x86 docker image on a M1 would take a significant performance penalty.
My Linux laptop locks up every now and then with swapping when I'm running our app in k3s; three database servers (2 mysql, 1 clickhouse), 4 JVMs, node, rails, IntelliJ, Chrome, Firefox and Slack, and you're starting to hit the buffers. I was contemplating adding more ram; 64 GB looks appealing.
I would not buy a new machine today for work with less than 32 GB.
