The search isn't on hold, we just do it differently nowadays.

SETI@home was great for its time, but distributing data to lots of end user machines just isn't the right architecture any more. Modern radio telescopes produce so much data, you have to process it onsite - these are pretty remote facilities, and the bandwidth out is much less than the bandwidth the radio telescope can produce.

Arecibo is also a couple generations ago - the Green Bank Telescope is more powerful, and the next generation of SETI is with the arrays, the VLA in New Mexico and MeerKAT in South Africa.

I wrote some other stuff about the state of SETI here: https://lacker.io/physics/2022/01/21/looking-for-aliens.html

There is Allen Telescope Array, https://www.seti.org/ata, funded by Paul Allen. It is radio telescope array dedicated to SETI and can do all-sky surveys.
