Yeah, the prevailing winds in Europe and North America in terms of fiscal policy are certainly blowing to the right currently, plus this is obviously also a subject that would get demolished in rampant populism. So I don't see this standing any kind of serious chance in political discussion for a while. As someone else said, though, you could hope for a serious roll-out in a European Nordic country (not another one of those unrepresentative test), and then have the (hopefully positive) results serve as an example in other countries.
Not that places like the UK or the US would ever take note, but other countries might, and here in Canada individual provinces might do something as well (although most welfare programs are run federally).
Actually, right now, the issue is rather that aging is leading to a lack of available workforce for all the jobs available. It will probably be a while before automization turns that around into a huge shortage of jobs.
Actually, the first political proponent (or the first high-profile one, anyway) of UBI was a conversative - cause for him, it's a way to cut away a jungle of government regulations while meeting the same target (and maybe meeting it even better). But then he probably has also been the only conversative to support the idea...
