Having people getting used to computers is not a thing that stops happening (short of people not having computers). Literally everyone who is born will need to get used to use computers.
Having computers imitate real world items is useful, because it provides a reference to other things rather than just being its own unique thing. This is useful even if you have never actually used it outside of a computer setting. A stereotypical telephone receiver icon almost always means 'call', even if you've never used a landline phone (much less one that's shaped like that icon usually is). Nobody has ever used a real-world hamburger menu, yet it's described in skeumorphic terms, since it's easier to explain and relate to.
You can reference other things without resorting to skeomorphism. Like using stars to represent favorites, typography to emphasisze/deemphasize things, the color red for warnings/errors, the color green for go/submit/ready, or the clearest of all: using descriptive naming in buttons and having self-documenting labels.
Skeuomorphic UIs absolutely have a place in things like games and tutorials for the youngest of children (like 5-6 yr olds, max), but past that, I honestly think labelling, a UI with feedback after significant inputs (like sounds, button states being extremely distinct, animations, etc), and not overcrowding the UI with too many controls and jargon will all go much further than skeuomorphism.

Screw the dyslexic and colourblind, I guess.
> using descriptive naming in buttons and having self-documenting labels.
Screw the non(-native)-English speaking in this case.
And even in the case that you're a native speaker, this is really hard to do well. You should try. Most fail.
I agree you should do these things, and many of your other suggestions (within reason) if only to give your users a better chance at understanding your software, but they cannot replace a solid grounding in the real world. We should have both.
What's clearer? [Call] or [(telephone receiver emoji) Call]?
That wasn’t my comment, and GP was presumably referring to things like headings being larger, not some subtle differences that dyslexic people would miss.
