For those who'd like a link to the paper: Preventing intrusive memories after trauma via a brief intervention involving Tetris computer game play in the emergency department: a proof-of-concept randomized controlled trial

I'm quite sure it wouldn't be hard for someone knowledgeable in developing Google extensions to create one to add these 2 options back. Seems like the steps here could do the trick.

There is no question in my mind that Twitter is within their rights to moderate their service as they want in order to maximize their profit. While I'll be interested in what Twitter defines as "hate speech". Yes of course, there is the dictionary definition, but then there's always a practical use of the word by extending its interpretation.

I personally use Twitter as a RSS feed to get news from researchers and news outlets and post by own. As a discussion platform, Twitter is shallow and only represents the result of emotional stimuli. I can hardly belief the number of times tweets are referenced by the media as sources about whatever subject they are covering at the moment. What could happen is that another less restricted Twitter-like service will appear, appealing to different groups unwelcomed users or users "feeling threatened" on Twitter. Each of these groups will live in their own echo chambers, both in the physical and virtual worlds.

What I am more concerned about is the constant self-imposed isolation of people to uncomfortable realities and opinions. The "Safe spaces", personalization of media consumed and block lists. While there are legitimate uses such as filtering shitposting, spam and insults, it will also be used by users to wall themselves in their own "safe" reality since they are in control of what they read and see. They are in shock when confronted with the real world and opposing view points. It seems Brexit and the elections are representations of the phenomena. I wouldn't be surprised to see the same reaction in European elections next year.

Filtering "hate speech" will not make it go away. While it may sound counter-intuitive to some, it actually need to be aired widely on the public space so any rational can be scrutinized and demolished with arguments. Those who persist in their claims without reasonable arguments and facts will found themselves - in my opinion - without any following and support. My question is thus, where can this happen nowadays? Private medias and universities are also profit-based and can choose conversations and debates held in their campus and broadcasts.

So in one word, how will Twitter arbitrate hate speech, will it be able to stay neutral or will it eventually fall under moderators that will decide what constitute hate speech? Yes, we should take step to make discussions more civil (and as it was mentioned above, Twitter is a terrible place for this) without just outright blocking it.

Anyone who has ever been frustrated with an automated telephone call support helpline, an alarm clock mistakenly set to 'p.m.' instead of 'a.m.,' or any of the countless frustrations that come with interacting with computers, has experienced the problem of 'brittleness' that plagues automated systems,

While true, I can also recount numerous frustrations originating from human interventions that lead to disaster such as initiating an emergency procedure ultimately leading to a nuclear reactor explosion, failed controlled burns or environmental disasters. Even in everyday life, trying to reason with a customer rep from bank A or government department B, can be as frustrating an unhelpful as trying to figure out which number I should push. As such, the existence of issues in automated system is hardly a justification disregard issues that keeping humans in the loop introduces, with the inconvenience that humans cannot be patched easily: they will keep making the same mistakes. I'd be interested in having statistics about the number of errors over a certain number of years between a fully automated system and human-included system to fully appreciate the benefits of one or the other.

While I'm all for overview and proper design, automation will become inevitable because of the advantages it can provide in certain type of conflicts - namely with technologically advanced adversaries. While some militaries may afford to have large amount of man-power and resources to maintain all these systems, countries with lower GDPs, large territories to defend, growing ambitions and lower ethical concern about consequences of potential errors will likely have automated defense systems to offset the support costs of human operators. In turn these systems will have a faster decision-making loop, providing an advantage over non-fully automated systems.

Of course the introduction of automated systems introduces the risk of hacking and thus the cost-saving of implementing automated systems will somehow go into stronger network defenses. However keep in mind that while totally possible to hack these system to actually leverage them against the users, this is not a trivial task either and requires skilled hackers, not your typical certification-hunting pen tester. However, network defenses are being automated as well, for the better or worst. A large chunk of network defense can be done by civilians (and probably will have to be given the competitive salary of the industry).

In any case, yes, we do need to careful with these systems and yes they have a lethal power, but so does many other systems, including systems with humans "in the loop". This should not prevent the development of automated systems, much like I don't believe it will stop the development of automated cars, planes and trains, much like it didn't stop the automation of the stock market despite glitches, which can also have tragic consequences. It needs constant testing, updating and training to new, unexpected issues.

Well I guess I won't have any ads on my lock screen until the next update restores Windows Spotlight as default...

And just to add to all other afflictions plaguing theses Olympics, a reminder that Brazilian beaches have above average (natural) radioactivity (ScienceDirect.com). I think the only thing missing is the announcement of a imminent meteor shower on Rio.

I was a late adopter to Twitter, and social media in general, mostly because I used to see them only as a mean for teenagers to share pictures of them eating doritos or doing duck kisses selfies. But then, as in anything created, I'm always trying to see how I could use things for meaningful purpose, and I found Twitter to be like a RSS feed on steroids. It allows me to get the latest activities from researchers, or quick knowledge on the latest vuilnerabilities without browsing 10-12 different websites. Yeah you have the occasionally shitpost or cat video, but every website have their low quality content, including Slashdot. I also find out it was a great way to share events, news and tutorials with my team quickly, as anyone reading something worthwhile would be able to share it without composing yet another email in my inbox with only a link.

Twitter, like any other social media can become toxic, mostly due to which topics you decide to follow or discuss. Especially topics that relies on belief rather than facts or data. Politics, religion, and pretty much any "-ism" are attracting loud and emotional participants for which the "feeling" of being right based on whatever show or blog they read, is good enough. No amount of logic will change their opinion. Unless you're ready to lose time and energy on these particular subjects, limit your connections to quality people and topics. I'd rather put my resources in place I can actually contribute something, which these people will never do.

Twitter or Facebook might go the same way as MySpace is now, however social media will survive in some form or another, especially as South-East Asia countries continue to connect to the Internet. They may become more regional such as Cloob, Weibo or BKontakt: people still need to communicate, despite the large increase of noise in the past decade. Like in anything else, it's a matter of adjusting your SNR.
