We've deviated quite a bit from the original post so I adjusted the thread title.

I think we mostly agree here, except you keep talking what FTx is and I keep trying to point out that it could be a lot different. Just because a particular mode is CAPABLE of being automated doesn't mean that it has to be IMPLEMENTED in a way to make that possible. CW and RTTY can be (and I think have been in the past) implemented in a way to make them fully automated as well.  The basic principle of software enhancement of a signal via precoding is not the existential threat to amateur radio that many seem to think it is, especially when compared to RTTY.  I have some thoughts on how a more flexible contest-focused user interface for an FTx-type mode could be designed that would support high rates and a degree of operator skill greater than I could likely handle.   If I can conceive of that so could somebody that could actually implement it.

As for merging social media and contesting, I've already stated that I don't particularly see the value in that.  What I DO think would be more enticing to young folks is if we could bring some of the fundamentals of online multiplayer gaming into ham radio contesting.  That could maybe include a more combat oriented scoring system, where I had the ability to affect somebody else's score as part of my activity instead of simply competing against the clock during the contest and comparing scores at the end ... except that I don't know how to do that (yet).  Another enhancement might be some way to integrate graphics into the contest, since one of the great appeals of gaming is the visual immersion.  I don't know how to do that either, but I know from personal experience that there are good reasons why young people massively prefer competitive gaming to radio contesting.  We keep ignoring that as though young people just don't understand, which is a foolish and self destructive attitude.

And to get back to the title of this post, an FTx-type mode might conceivably even facilitate the incorporation of the combat and graphics concepts I described in the paragraph above.

It is fundamentally a software modem, optimized for processing weak-signal data.

In practice, it is often automated.  I know of one significant 2019 DXpedition where FTx was used in fully-automatic, unattended mode at night.  There may have been others.  We all know there will be more.

This applies to all data modes, including RTTY.

Cool things can be done with DSP on all modes, whether at RF or AF. The bottom line is that FTx represents automatic (for most practical purposes), machine-to-machine, data processing over RF. All modes can be enhanced by DSP, but CW and SSB tend not to be automated.

We might equally translate the received text to audible speech. But why do it?

Yes, it is cool technology, but how many such simultaneous CW signals would be "QRM free"?  Some of us can still mentally decode individual CW signals in the presence of several others.  We choose to do things the hard way, for its own sake.

It also happens to facilitate automated unattended contacts.

All data modes, including RTTY, are essentially machine-to-machine - and each has its good and bad points.  What RTTY does have in common with FTx is that it can not be decoded by people.

This "whole new ballgame" needs an appropriate name, and I've already suggested "Data Processing Over RF".  However technically accomplished it may be, and however altruistic its designers' intentions, this ballgame now distorts and devalues the DXCC program, it de-skills both DXing and DXpedition operating, and it diverts those who don't know any better (and some who should) from CW and Phone contesting.  I consider FTx to be a WMD for ham radio.

As for the suggestion to merge social media and contesting - why do it?  When disparate communications media are merged, the dominant one usually wins out - and contesting is the junior partner here. Are phone apps anyone's idea of ham radio?  It seems to me that once ham radio becomes inseparable from the internet, it will have ceased to exist.
