I think it's probably because the headline called it a clone, which sort of implies 1:1 feature parity. It's neat, but it's not a clone.

There are plenty of "iPhone clones" that don't come close to feature parity, so it seems a bit picky.

Pedantic stupidity.

No. Wow. Clarification is not Pedantry.

Did not sound snarky at all to me. Very factual, and had a very minimal, neutral tone to it.

Also informative to people who don't know echo at all.

They're not commenting on the quality of Jarvis (an excellent project), but on the headline. One of the key features of Echo, and one which is essential for something like this, is a good microphone. Most off the shelf ones are useless for this, and so the Echo provides fantastic value by delivering not only the voice recognition/action platform, but the hardware to make it work well.

I'd challenge someone to make a practical device that leverages Jarvis. Most microphones just aren't up to it.

I will say, I find the trend of HN posts that say "clone" of some commercial product but are missing significant features to be kind of frustrating. It tends to devalue the work that's actually involved in creating successful projects - and thus the work of software engineering.

Reminds me of the coding horror post, "Code: It's trivial" http://blog.codinghorror.com/code-its-trivial/

It is PR to sell one of their products

It's open source :) https://github.com/monteslu/pagenodes
