What about the following encrytions⸮:

Why worry about what might happen in 4-5 years? It takes time, especially for the banking industry, to adopt new standards. Also, encrypted bank communications can be logged and broken later, so you also need some time to allow for sensitive information, such as credit card numbers, account numbers, passwords, etc. to change. When you consider all this things start to look a little more urgent.
Excuse me if this is a woefully naive question but as we have more and more devices available to us and connected to the internet would it be possible to combine something like DH with multiple handshakes with multiple devices we own. Compromising one connection is easy compromising 2-3 connections is an order of magnitude harder.

Why? If new math leads to a O(1) attack, cracking 3 connections would just take 3 times the time. There will be some practical issues in that one would have to I tercept 3 connections simultaneously, but that a) is outside of the maths and b) probably will not be that hard, since all that traffic starts and/or ends at a single point (e.g. your home WiFi router, or the bank's gateway to its systems)

It's funny that the URL of the researcher's website is http://www.prism.uvsq.fr/~joux/publis2006.html (the prism part).
