21 y/o engineering student looking for real bottlenecks in hardware/chip design worth solving
Hi everyone,
I’m a 21-year-old engineering student deeply interested in embedded systems, VLSI, sensor systems, tactile interfaces, wearables, spatial computing, and intelligent hardware products.
Recently I’ve been thinking a lot about industries where electronics/chip design still feels primitive or stagnant — not necessarily in terms of raw compute, but in terms of user experience, sensing, interaction, power efficiency, miniaturization, or physical intelligence.
For example:
tactile interfaces/haptics,
smart wearables beyond watches,
lighting systems,
grooming/personal-care electronics,
accessibility tech,
spatial awareness devices,
ultra-low-power sensing,
edge AI for tiny devices,
novel human-computer interaction systems.
I’m trying to understand:
What are the REAL bottlenecks in hardware today that are painful enough to matter commercially?
Not just “cool ideas,” but:
problems engineers repeatedly run into,
limitations caused by current chips/sensors/interfaces,
or areas where existing solutions are surprisingly bad.
I’d especially love guidance from experienced engineers/founders/researchers on:
industries that are technologically behind,
unsolved sensing/interface problems,
areas where a small team can still innovate,
or gaps where custom silicon/embedded systems could actually create meaningful differentiation.
I’m not looking for “easy startup ideas.”
I genuinely want to understand where deep technical leverage exists.
Some questions I’ve been asking myself:
What kinds of devices are still missing because current chips/interfaces are inadequate?
Which industries are still using outdated electronics architectures?
What areas are underrated but could become huge in 5–10 years?
Where do experienced engineers think young builders should pay attention?
I’d really appreciate any insights, hard truths, industry observations, or technical rabbit holes worth exploring.
