I anticipate that we will soon see the end of local computer systems.
It's funny that similar statements about "central" computers disappearing with the success of the
PC were being made back in the 70's and 80's yet now we have almost come full circle (the only
difference being that the technology has changed from central "mainframes" to central "datacenters").
Although you could be quite right I tend to think that the move to and from centralisation is one
that is likely to repeat. I have envisioned for many years the concept of the "home server" which
securely holds your private data in the security of your own home allowing secure access from
anywhere you are travelling without having to trust untrustworthy 3rd parties (and this makes
even more sense if you are also storing wealth in the form of digital currency on your server).
The more that companies like Google and Facebook use/invade every users privacy for their own
gain the more likely that the "home server" concept will take off.
