I don't think the average consumer will even know they are benefitting from AI directly. Any consumer product that advertises AI doesn't seem to use it for any reasonably important component. On the flip side, the breakthroughs that AI makes, particularly as it pertains to the speed of discovery, implementation, and adaption, of medical and scientific research will be huge for businesses. It's going to speed up competition and, hopefully, lower barriers of entry for new businesses since having some wise old sage will be less and less important when you can buy an AI tool that replicates 100+ years of experience in any particular industry.
I'm just spouting personal opinion, not based on exhaustive research or anything. But I think the biggest impact of AI for the average day to day consumer will be if their particular job gets replaced by AI. Otherwise, it will be mostly abstract except for fancier internet interactions lol.
