I have figured that I’m going to get exactly one CS hobby that is not work, and 0 CS hobby if I can find a job that fits the hobby.

Then I figured there are less than ten books that I need to read, and probably less if I can get such a job because it is always a lot better to learn on the job.

So I agree with the author that such subscription is not very useful, and a paper book + a paper notepad are way better than reading books on a tablet.
