As a person who accidentally posted sensitive info on chats, I welcome this feature. I do wish they implemented an indication "message deleted" in the chat to show that the editing took place.
To provide a truly secure laptop one need to control entire stack of software, which means OS verifying kernel module signatures, no third party software, BIOS verifying OS and MBR and TPM verifying BIOS (unless it's made truly read only which would probably require custom chip these days). Anything else would be an illusion.
I agree with the comment citing XKCD "You will never find a programming language that will free you from the burden of clarifying your ideas."
I see programming as a way to model reality. All programs essentially created to do something with objects of the real world or model existing world in some way. And that is where the complexity comes from. As we go higher up the stack of abstractions and tools, some things get easier, but the problems and tasks remain complex just like the world behind them. Performance gains we get come from the fact that many of the modeling and decision making has been done "at the level below" so we can shift into making higher level decisions.
Just imagine a "magic AI" which can create any program for you simply based on your description. For any non-trivial program which does not previously exist you would need to specify so many details that your list of requirements essentially becomes a program (in DSL). The more "defaults" and existing pieces you can use, the easier your job will be.
So, following that logic, the programmer of the future would be using some sort of AI for sure, to take care of the parts of the system which can be reused and recombined (taking care of the common details). And that means that anybody who can describe what they want will be able "to program". But for new problems, it would need to go into deeper down the stack and domain knowledge to be able to build new things.
In terms of "what you need to know" it means having domain knowledge so you can describe what you want. And for new domains - being able to dive deep and learn them, which means the more basic stuff you know (math, statistics, algorithms, whatever), the more efficient you will be in learning and ultimately building.
I would add that a big cultural difference in US from, say, Ukraine is that people avoid talking about money as a plaque. As if it is a bad shameful subject. I do not know where it comes from - pride, competitiveness, avoiding jealousy, lack of confidence or extrapolating work policies into personal life.
I think people lose a lot because of this. First, they do not let share their struggles with each other. Where I came from people used to complain and exaggerate about their money problems, but nevertheless they share. Without sharing, there is less emotional and practical support from friends and family.
Secondly, without talking about money there is less chance to learn and cooperate for successes. If my friend wants to do X and never mentions to me that, I have no chance of telling him what I know about it from my experience or from my other friends experience.
