Energy use will eventually come down, but AI systems will always need storage and memory. Companies like Micron, with a P/E ratio of 12, are more certain winners than those with much higher ratios who are likely to be disrupted or commoditised by software companies. I suspect HG Capital and other SaaS companies will become winners in the foreseeable future, as humans (and paying them) will still be needed alongside leveraging AI.
Timescale is important. For now, NVIDIA's results this week will be crucial for them. I suspect it will perform well for a while and remains a top 2 or 3 holding in my SIPP before disruption, but companies within HG Capital are still in the top 10.
Currently, software I use for my job, found in companies like HVPE and Atlassian, use AI and is useful. However, actually using AI to analyse qualitative data is a game-changer, as in the past, only quantitative data was queryable. If the qualitative data is structured properly, its power is remarkable.
To explain as an example on a basic level, what schools are doing is using AI to generate individual exam papers for students based on the examination board syllabus (and other trainings), then uploading the weaknesses of each student. This is a simplified but powerful example of AI in use.
Once we see use cases like this, it becomes easier to find new applications and uses by connecting the dots. For a creative like me, AI has been snowballing... and it seems that AI will eventually have to be commoditsed (cheap as edible chips), resulting in the current crop of high P/E companies in my portfolio (via ATT) being in a bubble. I am sure they know it but have little choice but to spend.
Edit: Apologies as this is going somewhat well off topic. Perhaps the Chinese know all this and events like DeepSeek was only a shock to the west playing catch up!
