DRB — I don’t want to get serious on a light thread, but. . .
Do you plan on living here long term, or are you just here for a few years? If it’s a short term deal, I agree with you. Or if you are retired and don’t have young children.
If not, it is probably well worth your effort to try to develop a functional Hebrew. It will make many aspects of your life easier, help with job opportunities, and certainly make a big difference if you have kids here and need to deal with the school system. If you don’t speak the language, you are making it much more likely for your kids to always be “outsiders”. I have met a number of people who made Aliyah many years ago who say they strongly regret not having put more effort into developing their Hebrew when they first arrived.
