Programming is still not intuitive (nor enjoyable) for the vast majority of people, and I believe it will stay that way.
Early on it was highly specialized, but from the 50s-80s it was generally expected that you knew how to maintain your car and would do the basic jobs yourself (oil, tires, maybe even filters). But now? A lot of people now would even call out AAA to change a wheel.
Those are but two of that millions of different jobs that are required for modern society to function.
And I don't see why programming has to be the ubiquitous pipedream over any other field, like philosophy. Of course, the main issue is that everyone is different and only a fraction of people are going to have an interest at all in a given niche.
The majority of people can't even do something that is universally uncontroversially good for them like exercise or stay a healthy weight. So I always thought it was funny to think that we'll all sing kumbaya over something that requires effort but with even less global appeal like programming.
Who said anything about being a great programmer? We have great writers, and believe me I'm not one, it doesn't stop all of us from gaining quite a bit from writing.
I'm not a native English speaker, I talk french. I'm far from great in linguistic, I'm not even great in English (my accent is atrocious and I require quite a bit of pause when I speak). Yet here we are and we both profit from me using that skill with you.
My sister has a criminology degree and one of her required class was SQL. She isn't a great programmer, yet she was able to use that skill to do more.
Personally I'm pretty sure programming should/will become a basic skill everyone will have. It doesn't means everyone will be great at it, it doesn't means it will fill every needs, but I believe almost everyone can gain from it. How many time have we used algebra in our daily life, I can count it without any hands for pretty nearly everyone ;) yet we all learn it. There so many time though that I saw people do repetitive tasks, that could be automated so easily on a computer, yet we don't learn that at school.
Not everyone will become full time programmer, but almost everyone can profit from that skill.
If you're doing anything complicated you have to wrangle the vehicle computer.
I expect you're right, computers will get more complex, more proprietary, less open, less likely to use open standards, companies will do more to prevent users adapting or repairing them.
