It's uncool to look like an alarmist nut, but sometimes there's no socially acceptable alarm and the risks are real: https://intelligence.org/2017/10/13/fire-alarm/
It's worth looking at the underlying arguments earnestly, you can with an initial skepticism but I was persuaded. Alignment is also been something MIRI and others have been worried about since as early as 2007 (maybe earlier?) so it's also a case of a called shot, not a recent reaction to hype/new LLM capability.
Others have also changed their mind when they looked, for example:

And in other fields, being alarmist has paid off too with little recourse for bad predictions -- how many times have we heard that there will be huge climate disasters ending humanity, the extinction of bees, mass starvation, etc. (not to diminish the dangers of climate change which is obviously very real)? I think alarmism is generally rewarded, at least in media.
Actually holding an x-risk belief is still a fringe position, most people still laugh it off.
That said, the Overton Window is moving. The Time piece from Yudkowsky was something of a milestone (even if it was widely ridiculed).
