I'm not quite sure SaaS is dead but I can't see the price not being depressed by AI clones.
Maybe hard to see "Workday" being replaced but I also never thought AI could one-shot all the stuff it does today.
Especially because you end up using half the features, building integrations, and working around all the limitations in off the shelf software - the cost benefit to just clone and get exactly what you need is hard to deny.
Yeah I think a few things are going to bite some people in the ass. Odoo, for example, is "open source" until you need "enterprise" things. Well, it turns out you can point a robot at it and just add those things on your own now. Bonus for releasing your fork under the same license as the community edition... Strange times.
