I feel like that really depends on how you view futuristic.
I think things with colored e-ink displays, USB C chargeable AA batteries, handheld emulators, 2230 NVMe drives, and USB C power portable displays are really cool but I feel like their availability these days has made them lose a bit of their futuristic luster. They would have blown my mind when I was a kid.
More niche products like Meshtastic and ESP32 Marauder devices are things I view as futuristic (and can be found for under $100).
The thing about meshtastic is the walking distance range and limitation to text messages.
Though I don’t know if it is possible to integrate a LoRAWAN concentrator with a nice collinear J-pole antenna to mount on the top of your house to move to a double digit range where it could be useful as a neighborhood mesh with multiple channels. (With the added benefit of using lorawan devices like pet trackers and things).
Still Lora smart (but local) home agriculture, water collection, etc… Is a really cool technology for large properties.
