GitHub Copilot
Reddit take
AI summary of the Reddit excerpts below — not a quote
GitHub Copilot is a polarizing AI assistant that users find highly effective for educational and boilerplate tasks but frequently unreliable for complex logic. It is widely praised as a 'study buddy' for IT certifications (like CISSP and Azure), where it excels at simplifying concepts and creating mnemonics. However, professional developers often report significant friction with its IDE integration, citing performance lag in Visual Studio and a tendency to 'hallucinate'—such as inventing log data or providing malformed code. While it speeds up documentation and unit testing, many users caution that it requires constant supervision and often takes multiple prompts to reach a useful result compared to other LLMs.
Pros
- Excellent for certification prep, simplifying complex technical concepts, and generating practice questions.
- Speeds up repetitive tasks like drafting documentation, unit tests, and boilerplate code.
- Useful for brainstorming architectural advice and creating memorization mnemonics.
- Helps fill knowledge gaps for students by breaking down topics into simpler terms.
Cons
- Prone to hallucinations, including inventing data in logs and providing malformed regex or code.
- Integration in Visual Studio is reported to cause UI clutter and significant IDE performance hangs.
- Can be slower than manual coding for complex fixes, sometimes getting stuck in infinite loading states.
- Often fails to provide useful advice on the first reply compared to competitors like ChatGPT or Claude.
Caveats
- There is a frequent name collision in search results with a car-buying app also named 'Copilot.'
- Some users report that standard IDE features (like scaffolding) are being removed to force Copilot usage.
- Reliability for 'truth' is low; users describe it as a 'slop machine' that prioritizes plausibility over accuracy.
Best for
- IT professionals studying for certifications (Azure, CISSP, O365).
- Developers looking to automate documentation and basic unit test generation.
- Users who need a tool to quickly summarize or simplify technical documentation.
Avoid if
- You require high-precision code or data analysis without the time to manually verify every output.
- You are sensitive to IDE performance issues or prefer a minimal, uncluttered UI.
- You are working on complex, multi-step debugging where the AI often loses context or provides incorrect logic.

Windows’ Copilot integration is about as smooth as a gravel road
I asked copilot to read through a log and it actually just made up data..
Even though both copilot and chatGPT find the same errors/warnings, copilot always fails to provide useful advice on the first reply
Parent context: I asked Copilot to generate a modified Hal Higdon plan for me. Reply: your slop machine — which is concerned with plausibility, not truth — generated a valid plan which on a surface looks like Higdon’s but doesn’t actually follow how he’d program one.
There are already services that negotiate for you for a fraction of this and don’t get money from the dealer when you buy. See Copilot (car app, not coding thing).
Plug the model and budget into CoPilot (car app, not the coding tool). It’ll make sure only necessary fees/taxes are there.
Plug the car and budget into CoPilot (the car app) and they’ll make sure the OTD price is fair.
Most full-proof way to not get scammed is to go through a 3rd party car app (e.g. CoPilot) to work with dealers on your behalf until a price is fair.
Best advice is to outsource this crap to Copilot or a similar car app that will work with the dealer to strip all unnecessary fees.
Copilot (car app, not the coding thing) does this really well already. Sister used it and they took out a bunch of junk fees the dealer was trying to gouge her with.
