The Present problem of emails worldwide(not just Hillary's)

If Russian espionage wanted 1/2 billion email accounts worldwide and got them no matter how they got them it is important to know that whether or not you have a Yahoo account that if you contacted anyone through email to a yahoo account they also have your information too. If all emails of everyone on earth can be hacked, this might change how we see emails in general. However, the same could also be true of texting on smartphones as well, or What's app or whatever. Literally anything you type or record on the internet could be in someone's hands worldwide that will do things unimaginable to you presently with this information. Just thought you should be aware of this as we move into the future as cyber wars grow in intensity with supercomputers around the globe from now on.
