Dangers

The opportunities that AP technology will bring should hopefully by far outbalance the dangers presented here.

List of possible dangers that could arise with the rise of advanced AP technology

• non degrading waste recycling (envirounment)
• building up on flawed software design (wikipedia:Technical debt)
• vulnerability to malicious software. (See: self limitation for safety, ..)
• risky geoengineering going wrong.
• development of new weaponary (e.g. interfacial drive based kinetic energy weapons)
• easy production of explosives (e.g. solid sp³ nitrogen, solid quartz like carbon dioxide)
• easy production of simple poisons (e.g. HCN)
• easy production of drugs (hard for diamondoid mechanosynthesis though since it's basic form can't deal well with complex floppy molecules - see: synthesis of food)
• sharp edges and splinters (health)
• social and economic dangers like detrimental effects of rapid and imbalanced economic change
• social and economic dangers like globally declining birth rates at a dangerous rate
• uncontrolled replication -- reproduction hexagon
• an arms race ?
• unethical perfectionism
• negative side effects of attempted cleanup after nuclear accidents (finely dispersed nanorobotic devices in the environment violating the "keep in machine phase guideline")
• negative aspects of excessive surveilance
• undermining of the possibility of gratis open source hardware due to fear based overregulation
• ... [Todo: add further ones]

Waste

Albeit advanced APM has the potential to be an absolutely clean technology in production (since its primary waste products are only hot air and warm water) advanced APM would be a unprecedented wasteful technology in disposal if not built correctly since the products themselves must be considered waste once they become obsolete - and the products will become obsolete fast as we can see with today's pace of software improvement. Also the global production rate in mass or volume will be bigger since production will become so widespread and accessible.

• Recycling is not an option its an obligation that has to be thought of before creating advanced APM systems that can produce products that do not biodegrade in reasonable timespans.

• The two recycling classes of products: The ones that can be completely burned to gasses (C,H,O,N,S) &
  The ones that produce slacks when burned (containing too: Si,Al,Ti,Fe,Na, and the wole remaining periodic table). See: Diamondoid waste incineration.
• amorphous slack of various elements is hard to deal with since blind atomically precise disassembly of unknown structures is a very hard problem.
• there's no AP disassembly (at least its a lot harder to do than AP assembly)
