Really? Maybe if we do not care about robustness, elegance, coherence, consistency and generally anything beyond making a buck and leaving more waste behind... sure!
I use Notepad from time to time for quick notes and I have noticed exactly zero friction added to this "workflow". Not sure what you are talking about.
Not having an extra language to deal with and so many features being just a flag away is why I decided to go with QtWidgets for the GUI of a project I am working on at work. And it is so nice to use despite being very old. For the graphically intensive parts I am just using Vulkan. I understand this might not be enough for all types of GUIs though and just wish QtWidgets had some sort of GPU acceleration.
For me, being able to visualize 4D would imply that I can picture four mutually perpendicular axes, something which I find completely impossible for me to do. And I thought it is impossible for any human brain. It would be fascinating if I am wrong.
Linear algebra is pretty straightforward if you learn it properly. Lots of resources seem to confuse matrices with tensors and linear operators because the creators don't really have any idea what they're talking about. Do yourself a favor, get a proper math book and be done with it once and for all.
Thanks. Maybe I should have stressed this more, but what I had in mind was a more mainstream language suitable for everyday programming too. All the languages mentioned in this thread are great but they are not getting any more popular and you would not use them to build, say, a game or a linear algebra library, right?
