per the link, macOS won't include any scripting languages by default in the future. So the bored user will be less likely to stumble upon an intresting programming language on their macs.
I don't know if that follows. I think it's likely that Apple will include a new installer upon setup that is essentially a one step 'click to install XCode Developer Tools and the following languages:' then has a list of options including Bash, Python, Ruby, Perl, &c. But all that is conjecture because we don't know what they're going to do yet.
You'd have to be very bored and unmotivated to not install a programming language if you had even the slightest motivation to program (IOW, not a normie consumer). I understand what you're saying, but I just don't see how this would be a huge barrier to entry.
