How else is brain implant research supposed to happen? It's not surprising earlier attempts ended badly, they're putting things in brain matter. It's hardly pointless cruelty.
Brain implants are way more important than self driving cars and reusable rockets. The latter are useful economically, while brain implants are a necessary step on the path of upgrading humans beyond biological limits. In the medium term they would finally allow functional artificial limbs.
