Talking out of my butt but I am on board with IBM on this one. Grandiose claims with no evidence.

Quantum, eh? We are stuck with silicon for another decade.

Wow, I really don't understand any of this, I even tried reading the source article that was linked! I just don't understand it! Well, I understand that Google thinks they've developed the first quantum computer that is calculating something that silicon based computers practically can't do, but beyond that I know nothing!

I thought you could only keep a current quantum computer running for a microsecond (still enough for loads and loads of computations), so 200 seconds would be huge. But then again, I don't keep myself updated on quantum computers at all.

Google does not give many details - to be expected since there is a big race between IT giants to achieve first this technological breakthrough - but is it "real" quantum or just an emulator (quantum “logic” imitation)???
Also even if quantum computers will come to life some day this does not mean that they will replace "classic" silicon based computers (quantum computing is based on gold chips). Sure they will have a place in scientific research, whether prediction patterns, cryptography, nano tech new materials creation but for servers, applications for office and home, entertainment and multimedia silicon based "classic" computers will still be the most efficient and cost effective solution. So these "quantum" computers will not replace but work together with "classic" computers.
Also I die of curiosity (I am a physics engineer working in quantum optics field) to know how they solved the "noise" problem as specified in this article if this is "real" quantum on not logic imitation: https://www.quantamagazine.org/gil-kalais-argument-against-quantum-computers-20180207/
Quantum optics and quantum physics in general already gave us a very useful application from non linear optics theory: The Scanner/Copy machine so I think that quantum computing is next but let this be for real and not some marketing stunt...
D-wave is an example of quantum emulator and not "real" quantum computing.
Oh and there is also this problem:

And this is not the only program, I would bet my money on it, the US (DARPA) and many other countries / governments too search for quantum encrypted communication, if only to make their own comm as hard to decipher as others can, keeping balance. Especially in military environments, I'm fairly sure, there are already some computers / quantum chips which are faster / stronger / more qbits than google here claims to have as a new success.
Very nicely perceived boss. That's exactly why quantum communications are among the first and foremost on the frontlines of quantum science. There's many programs for this, in particular I'm aware of the Austrian scientists collaborating with the Chinese universities, and this already launched in 2016:

Hmm Interesting. Of course with all new technologies there are spin of technologies. I taste a time machine spin off here. 4 Dimensions and all. My guess is people from the future will travel back in time to take our JOBS>

As with any new technology you have to verify your claims but i take the view that this is a google marketing ploy to get an advantage over the competition at least in the short term until someone else proves that it can be done and then you provide your results so until that happens be a skeptic

Even if Google's claims are kind of far fetched, this is still very cool that a Quantum processor exists. Not that it's going to be ready any time soon, but can't wait to see development of this.

Coincidentally, they concluded quantum physics experiments which "reversed" the flow of natural things, as in heat going from something cold to something hot, making the hot thing hotter and the cold colder, implicating that the "arrow of time", and the natural order of cause -> effect could be turned otherwise around, or at least, looked at that way, and all...
