That's basically what Goldman is saying. AI might be up and coming, but it's not this year or next year. It's probably 10+ years out.
No, that's way too far. The internet didn't take that long to "happen", even if it wasn't full transformative after just like 5 years.
AI won't take 10 years, either. The impact and extent to which it permeates everything will certainly be greater, after 10 years, but it will be a matter of course well before then.
And yes same thing happened late 1990s. Cisco's stock for example, topped out around 77/share, plummeted to 10/share, and today it sits at 47.
Back then, it had the game pretty much to itself. If you look at it now, its marketshare has been nibbled away in various market niches, and it has been facing big competition & price erosion from Huawei. So, it no longer represents the market like it used to. If you look at the TAM where it plays, that has grown hugely over the same time.
Cisco simply grew fat, mainly because it could. Much like I expect Nvidia will lose its complete dominance of the AI market, in the long run.
Of course, then there's 3COM.
Yup. Back in like 1998 or so, I paid a couple $hundred for a 100 Mbps 3Com PCI NIC. Within 5 years, you could buy little no name 100M cards for like $25. In 2004 or so, I got a motherboard with integrated 1 GigE. Perhaps where 3Com failed was making the transition to higher-speed enterprise NICs, because at least a few companies seemed to do alright in the 10 Gig market.
However, if you look at folks making cable modems, that market seems to have done pretty well.
