Every successful technology firm has an R&D division of some kind. If IBM Research disappeared today, then it would be recreated tomorrow. Somebody has to do the groundbreaking work.
Where IBM has historically had big problems is in taking the knowledge from research, converting it into saleable offerings, and successfully selling it to the public. They don't easily do it. In way too many instances, IBM's go-to-market strategy consists of responding to RFPs or RFQs from well-heeled buyers with a custom bid. Supercomputers, AI, blockchain, whatever...IBM will do it, IF you know exactly what you want, IF you have access to IBM marketing people, and IF you have a lot of cash.
Sounds good right? Except that companies like Amazon, Microsoft, Google, OpenAI, etc. are creating supercomputing, AI and cloud offerings that are easily accessible by anybody with a web browser and a credit card. I'm sure they'll happily respond to RFPs or RFQs from the right customers, but it's not like you need one to deal with those outfits. Try working with IBM if you're a little guy.
