It seems you have some misconceptions about "philosophy". The traditional divisions of philosophy are physics, logic & ethics. Theoretical physicists, like Einstein, are actually "philosophers." Logic will never be obsolete, though it is always under seige. Same with ethics.
I don't believe philosophy is obsolete because of science and technology. Philosophy studies the nature of knowledge, reality, and existence, all of which are still relevant today, and will possibly remain so for the foreseeable future.
If by philosophy we mean thinking about the world and our place in it, then no. Science and Technology further our understanding of things like that. If we mean superstitious beliefs and unproven claims used to lower the standard of living for millions of people, then yes. Science and Technology are rapidly diminishing such fragile things.
Remember that Philosophy is questions that may never be answered. Religion is answers that may never be questioned.
