What a shame.
If Microsoft of all people (joking aside) cannot get this right then what can it get right? It has all the skills and the people to get this right but it is bowing out too early. They should have stuck at it. I have an Alexa but I also use Google assistant (voice and text). Both these platforms are at a very early stage and with a bit of effort (and focus!) Cortana could easily and should have competed with them. It is early days in this sphere and if MS bows out here then what the hell can it compete at? Ok, it has Windows, but it has got to be more than a one trick pony. They bowed out too early with a Java dev platform and other languages it didn't even try to make Visual Studio available for. They should be pushing VS for all types of development. Come on Microsoft - grow a pair!!
