It's not the type of thing I'd expect to find in wikipedia at all.
To be clear, I don't have a problem with technology X being in Wikipedia. Indeed I expect there to be a page, and it would probably be my first port of call for finding out more. My problem is with an editorialised list of 'Emerging Technologies'.
Here's a sampling of some other interesting list articles:
And the all-time best:
I, for one, am happy these exist, despite the editorialization, etc.
Personally I'm a Wikipedia maximalist, it should record everything. They seem to have decided on a different path, partly on notability grounds, partly on the basis that its done elsewhere. That's fine as far as it goes but be consistent.
Lists make sense in a lot of contexts, lists of songs, albums, monarchs great. List of 'best' songs, 'greatest' monarchs, 'emerging' technologies, less so.
