This has significant implications. Here is a fictional interview I wrote recently that discusses the technology and some social issues in a more informal style. If we can stick atoms together to make rigid structures such as diamond, we should be able to make atomically precise factories that can make copies of themselves.
Potatoes cost less than a dollar a pound.
The manufacturing process should be a lot cleaner than today's processes. And if you need to build more stuff, you just take your factory off-line for one hour, have it build a copy of itself, and double your production capacity. DNA under direct control. Power storage will become far easier and more reliable, allowing the use of solar energy for virtually all energy needs. Another Computer Revolution Computers will be more powerful by a factor of about 1,000,000,000.
