Sharpe ratio is just the start: it gives you a metric on your portfolio. If it gave an interpretation of what that means, or give guidance on how certain actions would adjust the Sharpe, that might add a lot more value.

I don’t quite understand the full extent of the AI will create jobs argument. In prior revolutions, say automation, automation created jobs because like building and maintaining robots is a whole thing. Building and maintaining AI is a whole thing, but if you’re talking about wholesale automation of intelligence, the fundamental question I have is:
What jobs will AI create that AI cannot itself do?
In the automation revolution, the bots were largely single purpose, the bots couldn’t be created by bots. There could and probably will be trillions of jobs created by AI, but they will be done by trillions of agents. How many jobs do you really create if ChatgGPT is so multi-purpose, it only takes one say 250k company to support it.

If AI is roughly where IT is in the 60's, we might see actually decreased productivity for a while until people (yes people) figure out how to use it effectively.

I love SICP, but in industrial software I'd point to "The Mythical Man Month".
rongenre commented on Ask HN: What hacks/tips do you use to make AI work better for you? · Posted by u/rupi
There's a couple uses cases (beyond the obvious) that I like with the chatbots
1. Brainstorming building something. Tell it what you're working on, add a paragraph or two of how you might build it, and ask it to give you pros and cons and ways to improve. Especially if it's mostly a well-trod design it can be helpful.
2. Treating it like a coach - tell it what you've done and need to get done, include any feedback you've had, and ask it for suggestions. This particularly helps when you're some kind of neurospicy and "regular human" responses sort of escape you.

Fundamentally a dev owns the code they write - it doesn't matter if it's copy/pasted from search results or filled in via an LLM.

Smaller notch? Touch ID? Better battery life? Faster charging? Larger default storage? Nope, let's skip all that and spend most of the event talking about video recording.
Is anyone here actually excited about the features they just announced? Or are people simply upgrading because they get the latest iPhone every year or two by default?
I'm on a 6 year old XS. When I upgrade, I get 5G and USB-C, and a chip that's now ahead of the OS.
I had a GSD who remembered everyone who threw a tennis ball for her. To the point that I had to warn people that if they tossed it once, she'd be dropping a tennis ball in their laps for the foreseeable future.
I miss that girl.
> Not saying these tools don't have a place. But people are using it without understanding what it is putting out and not understanding the long term effects it will have on a code base.
It is worse than that. We're all maintaining in our heads the mental sand castle that is the system the code base represents. The abuse of the autocoder erodes that sand castle because the intentions of the changes, which are crucial for mentally updating the sand castle, are not communicated (because they are unknowable). This is same thing with poor commit messages, or poor documentation around requirements/business processes. With enough erosion, plus expected turn over in staff, the sand castle is actually gone.
There needs to be a pattern for including AI-generated code, recording all the context which led to the generation.

It shouldn't be. There should be more education about why EVs are the clear choice.
EVs are the clear choice if you've got an ICE car as a backup.
I mostly do commuting, grocery runs, etc. EVs are great for that. But then I do road trips about once a year, and an EV just adds to the complexity of planning currently.
