“Our company is pleased to present you with mirror blinds on the windows! Reflection coefficient - 0.99! Electronic warning system for laser attack - included! Order now and get a coupon for a free installation! The system compares favorably to asbestos curtains with an aesthetic appearance, which is especially important for the interior of modern city apartments! ”- in similar words, it is possible that in the near future various ways of protection against "laser pointers" will be advertised.
My friend has a laser pointer, the laser power which sometimes allows you to hunt for cockroaches. There is also a more complicated device - a laser extracted in the 90s from a defense plant in the Leningrad region, with which it is not interesting to hunt cockroaches - they immediately become charred. And with whom he once ruined the tape recorder, too loudly turned on in the evening in the courtyard.

Of course, there is a difference between a pen-sized laser and a laser with a power supply. However, technological innovations that fall into the hands of users are becoming more and more potentially dangerous. For example, what can prevent the owner of a 1-2 watt laser from setting fire to a curtain in an apartment in the house opposite? Or "hunt" not for cockroaches, but for example, for birds?
There are also innocuous gadgets - pocket mobile phone jammers, pocket jammers of GPS receivers, pocket infrasound generators, etc. Practically for all of them, the principle “open the lid, solder the wire, and will become 10 times more powerful” (exaggerate, but not much.)
Actually, the forecast: sooner or later, the moment will come when walking with a “regular” gadget will be just as “bespontovo”, like using a DVD-drive with un-regional protection. And then ... (here you can fully dream up to the best of your skepticism) ...
What then? Laws restricting the burden of "transmitting devices"? Licensing of laser pointers through the police and help from a psycho-dispensary? In general, some kind of cyberpunk future is expected, if these processes and go to gravity. Although manufacturers of various kinds of "protection against .." obviously will benefit.
