Setting aside that it's a continent with widely varied tech scenes (UK vs Sweden vs Netherlands vs Greece vs France vs Bulgaria; the startup scenes in some of those are pretty impressive and if they had the same amount of capital thrown at them, they would rivaling SF), even the most legaciest of legacy companies (think 200 year old insurance companies or similarly aged industrial concerns) are modernising everything. Yes, there is more employment stability on average, and you won't get fired from a big bank for being slightly behind the bleeding edge, but if you refuse to learn and there is no static niche you're already good at (e.g. mainframes), you won't have a good time.
