We are still in the dark ages, though. Just consider: this "bulb" has to plug into the standard 110/230V AC electrical sockets. Powering an LED is nothing like powering an incandescent bulb: you need a constant current driver delivering a precisely measured DC current that, depending on the LED, is between 300mA and (say) 1.5A. The voltage you need depends on the number of LEDs in series, but assume 3.2V per LED. If you want dimming, you need to do PWM (pulse-width modulation).
This means that inside every "bulb" like this there is a small switching power supply. And small switching power supplies that can take you from 110/230V AC to 3-24V DC are a) expensive, b) not very efficient.
Even more amusing is the "dimmable" bulb: traditional dimmers in AC circuits use triacs to effectively cut out (e.g. cut to zero) a part of the sinusoidal AC waveform. Meaning you get a chopped-up sine waveform behind the dimmer. Any switching PSU won't really notice, as long as there is enough (let's use a technical term) "oomph" left in the waveform. So, what the "dimmable" solutions do, is look at the AC waveform coming in, notice that it isn't really a sine and a part of it has been cut out, estimate how much has been cut out, and provide a PWM dimming signal to the LED driver.
Sure, it's all still better than the incandescent bulb, but it's very costly and inefficient. It also generates a lot of waste: if you throw out an incandescent bulb, it's really just some glass and a little metal. The LED "bulb" contains at least 20 electronic components and a PCB apart from the LED itself.
I think that sooner or later we will need an additional electrical standard, 24 or 48V DC with an overlaid control signal for dimming and a new standard for sockets. 110/230V simply doesn't make sense for powering single bulbs anymore.
