The market is priced at expecting AGI levels of breakthroughs. Just a very useful tool for programming is definitely not enough to keep the music playing.
What does "AGI" mean to you such that we have not had it for years already? Whenever I see people mention AGI it's in the future tense, as if we don't have artificial machines that can apply intelligence to general domains.
AGI means that eventually there is just one profitable company left; but it is not clear at this point which one it will be. Also it's worth noting that the current market capitalization for the technology industry just in the US is around a third of a hundred trillion dollars (Which would be explained by the possibility of AGI emerging from another country/continent)
