The problem is, the whole house can hear it. Every keystroke, especially every carriage-return (those are like thunder). It beggars concerns about super-clacky PC keyboards disturbing people. I cannot imagine what typing pools and newsrooms sounded like in the 60s and 70s.
I really wish there had been a terminal or keyboard based on that. I like my UNICOMP clacky, but I'd gladly pay $1000 for a Selectric-feel unit.

"If you remember what it was like to type on an old IBM Selectric typewriter, you know about what the experience of typing on the DasKeyboard ($129) is like. The company actually had a couple of old IBM Selectric typewriters at their booth."

No. Not even close. Das use Cherry MX switches of various kinds, none of which feel like a Selectric.
My mother also had a Selectric, and I used it sometimes. I mostly remember it being loud.
I don't recall the keyboards being especially different, but I was just a kid. I do know that it utterly spoiled me for dome keyboards, which I always hated; I hauled that Model F around for about fifteen years, before going full-laptop for awhile. I still have it.
At which point the mechanical keyboard renaissance was in full swing, so I use an Ergodox now. Cherry-type switches are good enough, but if someone made an Ergodox type board with Model F type buckling spring keys (fat chance), I'd have my grail.
There are adapters you can bolt on to make them speak USB, but a lot of them are a significant effort of cleaning/derusting/repairing since many of them are "barn finds" in iffy condition. A nicely restored one will be in the 1-2k range.
I wonder if an alternative would be to take an actual Selectric, which are likely cheaper and more available, and tap into some part of the mechanism that parses the keystrokes and convert that to modern signaling. I could imagine a comical assembly that's basically one of the old typeballs with a few dozen contact switches, all wired to a Bluetooth keyboard module
My mother could type over 100 wpm on one back when she was a young woman.
I remember when all the administrative staff got them at our school. When I got to high school we wanted them for the school newspaper but got rejected. We were told they were a 'serious tool' and far too expensive for mere schoolchildren to be able to use.
"Over the past 100 years, hundreds of millions of IBMers, clients, customers and business partners all over the globe have helped IBM make the world work better. To every single individual, thank you. We pledge boldness in IBM’s second century to create a company that never stops moving toward the future. Ever onward."
Lofty speak, and not to be a party-pooper but I can't help but think, if we're getting all nostalgic about IBM history, then part of me just can't help but bring it up. IBM collaborated with Nazis and helped enable the holocaust which has been well document by Edwin Black. 
As the Nazis invaded a country they would perform a census to identify the undesirables to be removed to concentration camps. This was an industrial scale data management and logistics problem that IBM was uniquely qualified to facilitate. The fact that they did so is not contested although it is not spoken of often and surely does not condemn today's IBM. We should however take it as an object lesson in the double edged sword of technology and the warning that we must restrain firms that would have us think they won't be evil.
"...in the 2012 reissue Black presents a letter dated 1941 from IBM that directed a Dutch subsidiary to work with Dehomag — years after business with Germany was supposed to have ceased. Furthermore, according to Black’s 2012 evidence, Watson took a one percent commission on all profits made in business with the Nazis, and had to personally approve all expenditures on said business, such as bomb-fortifying Dehomag installations."
"What Hitler has done to us through his economic warfare, one of our own American corporations has also done . . . Hence IBM is in a class with the Nazis . . . The entire world citizenry is hampered by an international monster."
- Economic Warfare Section Chief Investigator Howard J. Carter 
Somehow that makes me think of the motto of a big tech company.
History is so inconvenient.
