Of course the media, including the BBC, likes to "hype up" the dangers of extreme flares: talk of wiping out satellites and power grids etc. All these things can occur, but we have better ways of protecting from these risks and with some advanced warning the dangers of black-outs can be reduced.
In many ways, I prefer the quieter years in the sunspot cycle: working DX with QRP is more challenging on the higher HF bands and, as I mentioned a week ago, WSPR will really be useful in winkling out the openings that fleetingly may occur.
