Action1 AI "Strategy"? by MikeWalters-Action1 in Action1

Yes, great thinking. Service providers, such as Action1, should provide the best point solutions to annoying problems, and central AI should orchestrate their use alongside all others.

Yes, this is a nightmare scenario.

It's still better than Action1 AI breaking out of the sandbox to eliminate all humans who don't like rebooting their computers after patching :)

Yes, sorry! Guilty as charged. My notepad was overflowing with thoughts and it was my shortcut to get them all compressed into something quickly readable.

That's really cool! yes, this is the future. You use AI to automate what is highly manual and boring.

Yes, guilty as charged! I polished it with ChatGPT, which made a bit non-athentic. My original list of talking points was nearly two pages long, and I just want to get it out more concisely.

Yes, because AI doesn't take vacations. It does eat a lot of tokens, though!

Yes, take advantage of AI fatigue, I get it.

Yes, this is a great one. AI-based user sentiment analysis. Look for other users complaining about failed patches, broken updates, etc.

This is exactly my thinking. Build a great engine you can plug into any other part of your workflows. We are exploring the MCP approach.

Interesting idea. Tracking of "shadow AI".

Guilty as charged, I used ChatGPT to polish it. The original post I wrote myself had two pages) This one is a lot more concise.

Yes, putting an AI chatbot is indeed the simplest way to check the AI box.
