It is digital technology specifically where we are seeing accelerating progress, largely because the progress compounds, using one generation's machines to design and produce the next generation's.

Also, most digital technology is developed outside of the government procurement / military industrial complex, so all the problems inherent to those systems do not apply.

If the Singularity is reachable, it doesn't depend on the ability to create aircraft or weapons of any sort, whereas it would be impossible to reach the Singularity without digital technology.

It's not accelerating, IMO innovation has stalled quite a bit.

If you compare the speed of innovation between now and 30 years ago, the change is quite dramatic.

There will not ever be a Singularity.

Why? Even if we upload a mind, even via whole brain emulation, that then becomes modifiable, optimizable. If uploaded minds start enhancing the process it can become a lot faster.

Sure, probably for them that will just look like how it looks now to us.
