Maybe in the future send an email with just a few simple words and phrases that then gets expanded by LLMs on the receiver end. A weird future awaits.

I hope it does not involve typing on a keyboard. Typing on a keyboard is so millennial, and holds back innovation, such as everybody solely using touchscreens in closed walled gardens. I hope the future is an llm that has access to all the context of our lives and then presents 4-5 such different keywords, and you just tap on the ones you want to use for the email. Once the llm is sufficiently trained, the last step can even be skipped and lead to the most seamless and obstruction-free email user experience possible.

Typing is a powerful mental exercise, with each keystroke contributing to improved memory, language development, cognitive adaptability, and concentration – all of which essentially breeds innovation.

The future you described is a wild kind of dystopia.

Mental exercise sounds exhausting and pointless. Think of all the possibilities that getting rid of such unnecessary distractions would open to the users, such as more time for scrolling down in social media and watching ads.

Obviously (dark) joking.
