I wound up doing something similar to this:
ARKQ - 27%
Botz - 9%
Microsoft - 9%
Amazon - 9%
Alphabet - 8% (ARKQ is ~4% alphabet)
Facebook - 7%
Tencent - 6%
Baidu - 6%
Apple - 5%
IBM - 4%
Tesla - 0 (ArkQ is 10% Tesla)
Nvidia - 2% (both Botz and ARKQ hold Nvidia)
Intel - 3%
Salesforce - 2%
Twilio - 1.5%
Alteryx - 1.5%
BOTZ and ARKQ are ETFs. They have pretty high expense ratios. You can replicate them if you want to save 68-75 basis points. Botz is pretty easy to replicate with only ~10K.
I'd consider adding exposure to specific company candidates most likely to participate / benefit from AGI, namely: Google, Microsoft, IBM, Amazon, etc...
Also, since you're betting on a pretty drastic outcome, which is very likely not priced in correctly into the markets*, you should consider buying options instead of stocks. The cost to you is much cheaper, it's easier to get more leverage, and they payout is much bigger for the extreme cases (in your favor).
* I gave a talk that touches on this point recently. The transcript should be up in the next few weeks.
For hardware, I can imagine a scenario where FPGAs become temporarily very important... This would be a period of rapid development into new types of algorithms that diverge from the capabilities of GPUs / TPUs, with such rapid and wild algorithm changes that new ASICs can't keep up. I dunno, it's just a possibility, probably not the most likely when I think about it.
Excellent question! Was thinking about it myself lately, especially after GPT-3 release. IMHO, it is really hard to say as it is not clear which commercial entity will bring us over the finish line, and if there will be an investment opportunity at the right moment. It also quite possible that even the first company that does it might even bungle its advantage and investing there might be a wrong move (seems to be a common pattern in the history of technology).
My idea is just to play it safe and save money as much as possible until there is a clear example we arrived at the AGI level (when AI completely surpasses humans on Winograd schemas for example), and if there won't be any FOOM try to find the companies that are mostly focused on the practical application where you get the biggest bang for the buck.
But honestly, at the point where you will have AGI widely available its quite possible that the biggest opportunity is just learning to utilize it properly. If you have access to AGI you can just ask it yourself: "how to benefit from AGI given my current circumstances?" and it will probably give you the best answer.
