No, not really. When you say "alternatives" you really mean "cool tech demos you can show investors to make them money-horny" like ChatGPT. Investors have no interest in sponsoring a sequel to ELIZA, a "racist Tay" from Microsoft revival, or really even computer vision unless you make it look sexy or put it in a particularly expensive weapon.

There are other things, but they're mostly toyish novelties like LLMs are. Unsupervised learning is almost entirely undesirable in most business applications. If your notion of "real" AI precludes neural nets and statistics classifiers then I am sorry to report that such «real» AI remains a science-fiction myth.
