The car analogy is worth pursuing. Cheap cars today are faster, safer, more comfortable and better in every way and feature than the best cars made 50 years ago, and in real terms they are certainly no more expensive. Car radios and even heaters were luxury extras in those days!
These improvements are now considered perfectly normal, and everyone accepts them - and buys them. The same has happened with other technology, including lighting, and no doubt improvements will continue. LED technology is already showing the way.
The stuff we CPFers regard as cheap trash today will simply disappear as better items become cheaper and more widely manufactured.
Even our cutting-edge lights today will seem antique in a few years time, as improvements overtake them. That is the nature of a competitive market.
