These guys are investing now because they are expecting golden mountains in two years. But the tech isn't guaranteed to keep expanding that quickly.
It could end up similar to the dotcom crash. All the promises of the 90s came true. But it took 12 more years, the smartphone and 3G/4G for it to happen. The realisation that it wouldn't happen next year was what imploded that bubble.
But that's a text book invest signal. You have market that is ready, and all you have to do, is educate, sell, or pour some money in startups that shape the message correctly to consumers.
In this case there's even more of that because AI has so many negatives for society too. Those will take time to deal with. It's not just about the message. In that sense the market is not really there yet. People have to see the value in this and they will do it in their own time.
Microsoft is putting a lot of pressure on this 'adoption' but it causes resentment at work, people don't like to be told what to do, especially by a vendor.
But the difference was the number of jobs replaced was limited to only a few categories and it happened gradually. AI stands to change things a lot faster and while I do think other jobs will emerge I doubt they will make up the full numbers of the ones lost and it'll also happen so fast that society will have a tough time adapting :(
