The old guard at Riverbed (original) were very future-focused but I believe their fallacy was that they were too far ahead and another example is SSL optimization quite a while back. Be aware, while sales does have a good "feel" for the future, they can also be wrong - eg., the Citrix optimization module.
The problem with Riverbed is no one understands anything else other than our own stuff. SteelFusion, unfortunately, is an example of having less-than-stellar thinkers because edge computing (ala Azure, AWS and probably GCP) is going to happen. We could've done well in positioning this product 4 years ago in the IOT and ML space - I think a specific SEM was mentioning this. BUT due to many folks at Riverbed "just not understanding tech trends", this boat passed us up and now the big cloud vendors are going to go with their own hardware product. As for SteelStore, that was FAR too bleeding edge and this was just bad marketing timing. If we had waited another2 years for AWS and Azure to mature a bit more, then we could've leverage this product as primary or secondary storage with a cloud back - sounds similar to Cohesity and Rubrik doesn't it - super large TAM's but timing (and survival) was executed better there.
At the end of the day, looking too far into the future can be dangerous, sales isn't always right, even the old guard Chief Scientist and CTO thought too far ahead. What we needed were better field technical leaders like the first line SEM's. Too bad at Riverbed, SEM's are trained to become dumb but there are a select few whom are very sharp and has that strong balance of tech trends, technical depth and hyper customer focus.
