That demo was very cool. But:<p>1. do we really want a centralised service for everything that has access to a lot of data within a walled garden?<p>2. Siri only works well with North American accents afaik (maybe all western accents?). Alexa&#x27;s voice recognition is the best and I hope Viv does a similar job.<p>3. This is mostly a personal preference, but for online shopping I prefer using a lot of filters. This UI doesn&#x27;t really help with that.<p>Also, HN probably knows better but is the &quot;computed plan&quot; shown in the demo, different from an execution plan created by an RDBMS?
