Ask HN: What technology do you think will take off in 2019?

Lol had to look this up online you never know, and JavaScript...just keeps getting extended.

Good joke :)

The natural complement to Webassembly: WebCOBOL.

- React and React Native will become even more popular

- Machine learning being used to increase accessibility; EA's recently-released blockbuster Battle Royale game Apex Legends includes a feature I've never seen before in any game; live transcription of incoming voice chat to text.. haven't relied upon it but I think it's an impressive first step in that direction

- Portable machine learning models, probably specifically real-time (24fps ~ 60 fps) computer vision image segmentation on mobile devices; this will go very well with the rising popularity of augmented reality frameworks

- Alternative non-monetary uses of blockchains, primarily for friend-groups or niche cultures - I've heard of private blockchains being used to broadcast locations of secret just-in-time-announced underground raves (in Berlin), so police can't just find out about it on facebook or something like that; this sort of replaces friend-of-friend word-of-mouth invitations and I guess you could implement fine-grained privacy/invitation rules this way

- Maybe Google Soli will become a thing - it likely won't, but it's still cool imo

- Software-defined radio and amateur radio in general

- 3D-printing, as mentioned by rolph

- Better IoT security practices, maybe IoT security frameworks, etc

- Better tools for circumventing digital censorship, thanks to the arms race between firewalls of increasing sophistication and those who want to circumvent them

- Increased recognition that data is bound by local regulation; Google in China, for instance, has to obey Chinese local laws. Perhaps we will also see increased acknowledgment of so-called "data embassies"

- Remote work and co-working will probably become even more popular

- Alternative non-monetary uses of blockchains, primarily for friend-groups or niche cultures - I've heard of private blockchains being used to broadcast locations of secret just-in-time-announced underground raves (in Berlin), so police can't just find out about it on facebook or something like that; this sort of replaces friend-of-friend word-of-mouth invitations and I guess you could implement fine-grained privacy/invitation rules this way

Isn't it computer costly apart from monetary purposes
