Venturing a guess. Its the hype of the non-technical automation crowd. APIs are hard for these people to grok and work with. The others are the engineering/dev/product crowd, the best among them have a high BS detector threshold. The former are a lot more numerically and its why the hype is so high.

Whereas the former see things talking to each other across boundaries with a minimal set up, the latter might look at it and see/say: "hard leaky abstractions"/"Poor security model"/"High $/task", you can't you build/sell it.

Where the latter crowd might exclaim: "Look my slack bot can confirm with my doctor when calendar appointment is near. SaaS tools are dead!". The engineering/dev/product are more sceptical and they are right to be so.
