Buffett's strategy is to avoid losses -- not to worry about missing out on possible gains. He believes you avoid losses by investing in companies with a long, successful track record of doing the same thing for many years and that are likely to continue doing that same thing for many years into the future.
So, it's not that Buffett doesn't "get" technology, he just can't make intelligent guesses about what tech companies will be earning 10 years from now. He sticks to his circle of competence and it works.
