I think the reason is people have different use cases they want a personal ai agent to do. And most companies have (incorrectly) positioned themselves as a personal assistant that can do everything.
And invariably they canât.
I think the winner is going to niche down, build an agent that does one thing exceedingly well and slowly add use cases over time. Until they can credibly say this does 99% of the tasks people expect an ai personal assistant to do.
the reason that nobody is using agents is because they are still wildly unrealiable even including the wildly expensive frontier models that are far too expensive to put in a mass-market consumer product
the reason it works for coding is because you have a six-figure-salary subject-matter-expert resource sitting there babysitting it all day (and still shipping slop)
