The 2nm claim is all marketing. The smallest features on these gates is much larger. For example, the gate pitch (what this measure used to refer to) on the 2nm process is actually 45 nanometers.

Nature's machines, for example, for reproducing DNA or for photosynthesis, are in a totally different league of 'precision engineering' to anything that our brightest engineers have ever created.

At times we get all giddy because we have invented a quartz clock, a wheel, a straight line or a calculator that seems to be better than anything in the world of nature, however, we sometimes have to overlook nature or forget to question why nature didn't evolve such things. With the clock, every cell in our body has some 'timing circuitry' tied into day/night cycles, seasons and much else. We just insist on doing it our way and proclaiming it better.
