Hi Gabby,
Welcome to the forum. In it's broadest sense, philosophy is interested in the meaning of life, but most modern things that get called 'philosophy' are a lot narrower than that, so don't be too disappointed! Also, you'll end up with more questions than answers, probably, but the journey is important. Philosophy can't decide everything for you, and some things are left up to personal choice or even faith.
As for modern technology, philosophy's got nothing against it as such. What did you have in mind? Perhaps you could start a thread and expand a bit?
