Living in that sort of bubble must be very uncomfortable. Companies from virtually every category are pouring money in OpenAI starting with Microsoft. Just go and take a look at their partners and which field they belong to.
And remarkable that you cite Microsoft's involvement as some sort of standard of significance. A company that has a long history of non-innovation, alongside its disgraceful history of suffocating and extinguishing actual innovation. Founded by one of the most remarkably unimaginative and predatory individuals in the software industry. I'd suggest seeing Microsoft investing in anything is only a good sign of a potential future rort (Gates' whole history of making money).
Finally, maybe rather than just saying that 'all sorts of entities are investing in this hoopla', try to make an actual case yourself as to what the value case in this technology is. We should try to think for ourselves here, not just follow the (investing) herd.
