Just a reminder from the viewpoint of IT security :
Can you imagine what kind of cybercrime potential will be awaken when (in theory) everyone's wallet (assuming global mass adoption) is more or less online for daily shopping purposes - and BTC would be priced @ lets say... 10000$ ?
Given the already dire security record of basically all established mainstream Operating Systems, lack of knowledge by their users and the knowledge that certain intelligence agencies have backdoor keys to most of these systems... Oh boy, that'd be quite a show to watch.
In theory, 1st assumtion (mass adoption and/or further increased BTC pricing) may come true within a few years.
2nd assumtion that would need to follow to prevent mass mayhem (massive increase in IT security and security awareness by every joe sixpack).... not very realistic IMHO.
Now that's something to watch out for. I don't even want to speculate how many zero day exploits would be rewritten to specifically target wallets. That'd take the term "cyberwar" to a whole new level.
You do know there was a time before antivirus software? People said the same about the internet.
You do know even today's most advanced Antivirus software catches at best (!) some 95-96% of typical viruses, worms and trojans, but far less than 50% of specialized/uncommon malware and only works a minimum of 3-24 hours after these malicious pieces of software have been reported, analyzed and included into updated definitions in the first place ?
(and I'm not even talking zero-day exploits there, against there is extremely little protection, nor do I talk about non-updated/exploited browsers or plugins or backdoors etc.)
btw. the time between networked IT on internet and viruses/antivirus software was fairly small. Today we have antivirus products that evolved for over 2 decades designed for allways-online systems and they
still don't offer any adequate protection to high-risk IT components whatsoever.
Additionally, the software today in the very best case merely tells you "oh crap, you're infected" or "virus detected & removed! (never mind the 20 other viral components downloaded and running undetected in the meantime) - plus the Antivirus software commonly isn't even able to clean a system anymore...
I won't even venture into that any AntiVirus software can easily be rooted & disabled without you ever knowing it.
Good luck risking your financial portofolio to some antivirus software that's nearly always late for the show, if you'll notice at all before it's too late.
That false sense of security and blind trust in future developments (nah, they'll fix that I'm suuuuure) is one of the greatest dangers to everyday IT -
today!. Never mind that getting worse by a hundredfold in the described scenario...
PS.
When people warned about the risks of permanent network connections - they were laughed at as "conspiracy theorists". Now these "nuts" get paid 6 or 7-digit sums per year and are among the most highly sought resources in IT security... Go figure who was right in the first place, the sheeple learned their lessons (as usual) the hard way. Seems intense pain is the the only thing that kicks some form of learning curve into them - as usual.
