The luxuries you have to not know a thing about enterprise grade servers because your world is JavaScript was made possible, (…) by people working on layers that do require familiarity with the underlying hardware.
That’s kind my point… Since everyone is or will be coding on Javascript (or other languages that run on virtual machines / “layers”) general developers won’t have a problem running on ARM datacenters anymore. Big cloud providers will take the opportunity to move to ARM as it is cheaper for them.
And btw, the people making JS fast and stable on ARM are, most likely, not that familiar with server grade hardware. They’re optimizing for phones and whatever where ARM was born.
