This does not really apply to me because I tend to bind boringness/excitement to problems and not technology.

For example if my task is to create a typical website, that is relatively boring by default. Speaking about databases I choose postgresql not because it is boring but because that is the most convenient, elegant, and general-purpose solution I know. I dont't get excited about NodeJS or MongoDB by default. What I get excited about if I encounter a hard problem: maybe a very hard scalability issue that is impossible to solve with PostgreSQL. Searching for the solution to that problem is interesting and then I might get exited about some NoSQL solution. Also I don't really get excited about new programming languages as almost all programming languages try to solve the same problem. On the other hand I got excited about recent advances in Deep Machine Learning (and frameworks like Caffe, cxxnet) because with these new advances and tools it is possible to solve problems which we had absolutely no chance previously.

Also it is pretty standard for me that the stuff I do at the workplace is relatively boring, and the stuff I do at night by myself is exciting.
