Good morning to everyone who sees CFA and thinks confirmatory factor analysis, not chick-fil-a

[Darby Saxbe @darbysaxbe]

I need people to understand how difficult it is to get an NIH grant. You spend months writing a proposal, following strict guidelines that include a detailed multiyear budget, bios of everyone on your team, plans for participant safety & ethical conduct. Then you send it off -1/n

I made a simple GIF using #RStats showing how changes to the a and b parameters in the 2PL IRT model change the shape of the function #IOPsych #DataViz

This reads like the opening to a movie.

AGI is near.

LLMs are good at coding tasks in part because they’ve ingested answers from sites like StackOverflow.

Will LLM performance suffer as the number of StackOverflow users declines?

I imagine we’ll notice a decrease in performance on questions regarding new stats packages and tools

[Santiago @svpino]

StackOverflow is a dinosaur that's going extinct.

I mostly use Copilot, ChatGPT, and Perplexity. I haven't found a single reason to visit StackOverflow anymore.

StackOverflow can't compete, and I don't see how they can stay relevant any longer.

I use Copilot for inline suggestions. As I type, Copilot takes care of the little things. It saves me from dozens of searches every day.

ChatGPT is the workhorse. I use it to solve more complex tasks with my code. Here are some examples:

• Explain what this code does
• Simplify it
• Rewrite it in a more efficient way
• Rewrite it in a more readable way
• Replace the use of a library with another
• Write documentation for it
• Describe potential edge cases
• Write unit tests for those edge cases

I use Perplexity to ask questions. Google is broken. If you don't believe me, try Perplexity for a day.

(Google is still king as a navigation tool. I never type a complete URL in my browser. I google it instead.)

Modern AI-powered tools are replacing boomer tech.

StackOverflow is dead to me.

@pcxd13 Interesting!! Not the effect I expected. Enjoy your vacation ✨

8/8 How can we develop our own drive for continued learning and understanding? How can teams identify instances where skill maintenance and development take precedence over efficiency? What other questions should we consider? [End of Thread]

[Riley Hess @RileyHess27]

1/8 🧵 Will generative AI stifle skill development in knowledge work? 🤖 Tech like #ChatGPT can take over numerous tasks. Is there a cost to this convenience? Do we risk losing our hard-earned skills and preventing the development of new skills? #ArtificialIntelligence

[Riley Hess @RileyHess27]

7/8 Think of pilots, for instance. If an automated system fails, they must intervene manually. The absence of skill in these critical moments could be disastrous. This showcases the importance of balancing automation and manual intervention.
