Chat bots don't belong to an e-commerce site; chat bots belong on the outside, specifically to comparison-shop and pull in some external information to de-bullshitify offers, correct "mistakes" and "accidental omissions" in the listings, resolve the borderline-fraudlent crap companies play these days with store-specific and season/promotion-specific SKUs with different parameters all resolving to same model/make name (think Black Friday/Cyber Monday deals that are not actually deals, just inferior hardware with dedicated SKU).
Agree. AI is (currently) fantastic at "de-bullshitifying" the internet. "Give me a table that compares Products A & B by z, y, and z." Companies have gone out of their way to make comparison shopping near impossible. Specs are hidden, if they're shown at all. Just figuring out if a certain TV had an ARC-HDMI out required downloading the manual.
I dread the day when ads inevitably make their way into the main AI models. One of the things its currently good at will be destroyed.
But the chatbot will take as a source the comparision data provided by companies! It's very common practice for a company to do some SEO articles with comparing them to their competitor like "FooSoft vs BarSoft", with things like "FooSoft has instant support 24/7, Barsoft has tickets that take 24 hours.."
