I actually find it to be a gamble. Alexa and other "AI" programs (which really aren't even AI...people are merely fond of using that term) simply pull and aggregate data from myriad sources and spit them out. Problems may arise when questionable data is pulled and used.
As Abraham Lincoln has pointed out for over 20 years, "You can't trust everything you read on the Internet." The majority of these programs retrieve both erroneous and accurate data and provide results. It's nothing but a modern-day - yet very fast - garbage-in/garbage-out data retrieval tool. The key is to gather accurate and authoritative data to help with any diagnosis.
Things like "P0---" DTCs are standardized and pretty well-known. Not a lot of danger there. On the other hand, you can often find wild variations in torque specs and other essential vehicle information when scouring the Internet. That's why when checking "Google AI" for an answer, there's always a disclaimer at the end of the text: "AI-generated answer. Please verify critical facts." No kidding...
Your best sources for information will always be authoritative sources, not an amalgamated mish-mash of crap from the web. Grab a factory service manual for starters. They're made by the people who built the cars...people who tend to know a little more than a computer program. Another authoritative source is someone who does the work for a living and has made the fix you're attempting. YouTube videos can be a wonderful tool here; however, you have to be able to discriminate between a competent professional mechanic and a hack.
"AI" (and again, what 99% of people see is not AI) can indeed be helpful to speed up some mundane tasks. It will not "take over," "escape," or perform any other science fiction horror story scenarios.
Use these tools, but verify the data. Or simply use authoritative sources from the get-go and skip a step.
The real danger, of course, is the fact these tools tend to further dull peoples' problem-solving and critical thinking skills. It seems over half the population can't read, write, spell, or perform basic math. Critical thinking skills have been destroyed for over a generation. The response is always, "Why should people have to do any of this? Their little machines do it for them, right?"
