The Vital Role of Exponential Growth in Technology
The role of exponential growth in technology is one of the reasons we will ultimately win the war on aging. Ray Kurzweil, I and many others continually try to explain the role of exponential growth and this is my attempt to get the point across. Regardless of how it is looked at, I simply cannot see that any argument against the exponential growth in technology can possibly make sense. The reason is simple, history just does not support any argument against the theory because we need look only at the past the rate of progress to see that it has always been continually accelerating.
To explain this whole idea, let us just start with a $1 bill and double it each day. After a week you would have $128, not a lot but a significant increase. In another week you would have $16,383. It is now that the growth pattern really starts to kick off because, by the end of week three, you would have $4,194,048 and the next week you would have $27,574,274. Yes, heading for thirty million dollars. Five days later, you are drowning in cash with $882,376,768!
The growth from here just keeps accelerating faster and faster but the vital point to keep in mind is that the first week only took you to $128. Now, three weeks later, you have nearly a billion dollars but you only need five more days and you have over 14 billion! This is the nature of exponential growth and it is exactly what is going on with technology and has been since the very beginning. You hardly notice the growth at first but the effect becomes increasingly clear over time. If we take the last century, it did not equate to 100 years of progress at today's rate but was around 18 or 19 years because of the rapidly accelerating rate of progress. I estimate we will make more progress by the mid to late 2020’s than we made in the entire 20th century and that we will see it again by the mid to late 2030's.
Ray Kurzweil loves to play with the figures relating to exponential growth and he has more of an understanding of this area than anyone else I can think of. What to me is very apparent (and maths is not my strong point!) is that Ray Kurzweil is correct when he say that the power of technology per dollar doubles every twelve months and that the rate of growth is accelerating. It seems likely based on exponential growth that our technology will be over 1000 times more powerful in just 10 years - and a billion times more powerful in 25 years.
Getting the whole concept into perspective
To get this in perspective, think about technology in 1910 compared to 2010. We had no antibiotics, we had just taken to the air, cars were basic and there was no TV, in fact virtually no technology that is familiar today. Now think what the result would be if we had technologies a billion times more powerful than we do currently. But what if the theory is wrong?
like Ray Kurzweil, I do not believe it is. Bear with me and I will
show you why. If you look below at the list of discoveries since 1041,
which are deemed to be the most important, you will see that 74 were
made in the 857 years between 1041 and 1898 and 41 of these were made in
the 19th century. Now look at list 2 which lists the groundbreaking
discoveries made in the last 107 years and you will see that the number
of discoveries in the 19th and 20th centuries are about the same but the
importance of the discoveries in the last 100 years is much more
significant in many cases and they are coming faster and faster.
It does not matter whether you personally agree or disagree with me, what matters is that the date of breakthroughs cannot be disputed and you will see the closer we get to the present the developments are coming faster and faster. Not only are they coming faster they are becoming ever more influential. I am confident that I am correct when I say that, even if the rate of progression slowed by 50% or even 75%, the rate of technological progress in the 21st century would still eclipse everything that came before it. If anyone has an argument that contradicts this I would love to hear it but I think the list below makes it much clearer better than any individual possibly can.

My predictions for the future
In January 2008 I made a list of predictions concerning the progress of aging research. I will not list them all here but will gladly email the list (with progress to date annotations) on request. Anyway, here are the big six predictions that I will make rather than bore everyone with the entire list.
2011: Conclusive Proof that we can influence lifespan in a mammal (this one was 2 years early in July 2009 see Rapamycin
2014: An Anti Aging compound which has been shown to conclusively slow the aging process is in phase II trials.
2021: First indications from researchers that RMR (Robust Mouse Rejuvenation) research has yielded significant success.
2023: Initial trials of RHR (Robust Human Rejuvenation) confirmed beyond doubt.
2025: We begin to approach life expectancy escape velocity where progress will lead to us adding 12 months or more each year to remaining life expectancy.
2035: Life expectancy becomes to all intents and purposes infinite through repeated rejuvenative interventions.
Before ending this page I just want to clarify one point. My prediction for 2035 that we could live indefinitely is not suggesting we will have cured aging only that we will be able to control, repair and mitigate its effects. Whilst the end result is similar in that you could live for hundreds of years, it is far from an actual cure. What this means is that aging like HIV/AIDS or hypertension today becomes a chronic but manageable condition.
If I stick my neck out and hazard a guess, my estimate for the timescale when we develop an actual cure lies somewhere between 2100 and 2150. It might be sooner than 100+ years but doubtful because we need to understand a great deal more of the underlying processes and human metabolism which is an area of knowledge in which we are currently not very strong.
Short Term Objectives
My final word is that our short term objectives must be as outlined below:
2015 - 2020: Move as quickly as possible to develop an intervention that delays aging and buys an extra 7 years or more of healthy lifespan. This would yield vast savings to health budgets worldwide and although it does not sound significant it will be a significant step in the right direction and raise public awareness of the potential benefits of future anti aging therapies. Unfortunately as I explained before, drugs which simply slow aging are essentially a dead end in the long term but in the short term they are a potential lifeboat because they will enable some older people to survive long enough until more robust therapies are developed.
Early 2020's: Implementation
of early rejuvenation therapies such as gene and stem cell therapies
when they become available. It is my guess stem cell therapies will play
a huge role because we are already making rapid progress and
implementing treatments in this area and stem cell therapies, develops in immunology and cancer therapies are showing significant progress when I wrote this in November 2014.
The interventions I am outlining here will initially work in conjunction with improved versions of pharmaceutical compounds which were first developed in the last half of the previous decade to retard the aging process.
Mid 2020's to 2030's: The first treatments arrive in the mid 2020's which can repair damage laid down by the aging process and effectively restore most body systems to a more youthful state. At the beginning these treatments will be strong in some areas but weak in others but exponential growth will now play its role and progress will accelerate rapidly. I am confident that once this stage is reached we are all pretty much home and dry because it now becomes just a question of living long enough to take advantage of each further breakthrough as it unfolds.
