Admittedly, mobile use isn't as easy as Notion, since Emacs does not like to cooperate with mobile devices (and I'm not a fan of Termux), and while Orgzly might be useful as a task tracker, it's not so good as a second brain. But these are not so big a problem in my case.
ChatGPT may not be the most reliable about giving answers to questions, but it still has value when studying.
For example, I'm currently seeking to reach a higher level of knowledge in Python. I use ChatGPT in four different ways.
First, I ask ChatGPT to provide a list of topics that are required to master a specific area of knowledge. So, for example, I have "procedural programming in Python," "modular programming in Python," "object-oriented programming in Python," and "functional programming in Python." The results show some overlap, but that's fine. Then, I repeat the question to further break down the topics.
At this point, I have a pretty comprehensive outline to work from. For each item in this outline, I ask for a summary of the topic. Admittedly, this is where wrong information is a risk, but that will be filtered out as I continue to study.
I then ask ChatGPT to generate 10-25 exercises (depending on the ubiquity of the topic) that cover that specific topic (making sure to specify that I don't want them to be answered). With this, I now have a list of topics to study, an idea of what I expect to learn, and a list of exercises for each topic to use toward that study.
Then, while going through the exercises, I will ask questions when I get stuck. If it gives wrong answers, that will become apparent when the exercises continue to not be solved, but at least, it's a start.
The point is that Steam is putting time and money into expanding the Linux gaming platform, even to the extent that they have their very own operating system (SteamOS) based on a Linux kernel, and are actively developing the workaround for Windows games (Proton).
You do not do these things if you want Windows to dominate the desktop. This would be a waste of money that would better be used solidifying their already-significant hold of the PC gaming market in a similar way to Epic, EA, and Ubisoft.
Marriage is the triumph of imagination over intelligence. Second marriage is the triumph of hope over experience.
