When we talk about these types of topics on the Internet we are usually all speaking about slightly different things. For example "Coding will be replaced by AI" can be interpreted as 100% (every programmer) or partial (X%).
When we talk in the 100% sense the bar AI must achieve is MUCH higher than replacing some percentage. To replace 100% of programmers the AI needs to not only be on par with principal engineers but also be able to understand domain, real world implications, stakeholder input and a bunch of other goodies engineers do behind the scenes other than writing code.
When we talk about the partial percentage, the bar is low. Companies already take shortcuts such as outsourcing or greenlighting a proof of concept for production without proper design. There are MANY terrible programmers employed today who produce code slower and worse than even the halicigenic mess that is today's modern llms.
The budget for replacing these subpar programmers is proportional to their salary. If we choose the arbitrary pay of 75k for these programmers, that means we could spend up to 75k on AI compute costs per year and still break even. This doesn't even need to be fully autonomous as the remaining senior programmers will be expected to pick up the slack whether they want to or not.
Tldr;
AI will definitely replace some programmers but not all programmers.
These comments are all so aggressive, let me try answering this in a less rude way.
App is short for application, at the end of the day no matter where you install an app from an app is a packaged chunk of software meant to accomplish a task. Microsoft word is an app, chrome is an app, flappy bird is an app, calculator is an app, any "program" that you launch is an app.
Now where the waters get muddy is app stores. App stores such as the apple store or Google play are apps specifically built to help you install other apps. The intent of these is to provide users a safe location they can search for other apps and install them without fear of viruses and receive updates automatically. Windows and Linux have their own app stores too, the windows store, though sad and decrepit is supposed to provide the same assurances as Mac's app store.
Now can you use the computer without apps? Yes! Your computer just won't do much since you've forgone your calculator, games, and any other purpose built software you might have installed.
Can you use the computer without the "app store"? Yes! You can install the application from anywhere, it doesn't need to be the app store. Apple and Google get a cut of the money made by apps sold on the app store. Because of this they are incentives to discourage users from installing apps from elsewhere. They've called installing apps from elsewhere "side loading" in order to make it sound scary and not normal but it is in fact the normal way we have been installing apps since before these app stores arrived.
The last type of app I want to call out because it's a bit different. Web apps are apps you can use by going to a web page. These apps are installed on someone else's computer and you get to use it when you open the page. It's still an app, you just don't have to install it. There are special types of computers (for example. Chromebooks) that are built around these types of apps.
Hope this helps!
