multiple problems: distance, temperature, water, funding
the discovery of exoplanets many light years away means: we shall take good care of our blue planet and share it peacefully and instead of putting all efforts into destroying each other and all life on this planet – we need to become a multi planetary species – just as Elon Musk says – starting off with Mars and going further from there.
It will require enormous efforts and i always wonder why SpaceX is so lonely when it comes to funding such efforts – because this is in the end what hinders mankind to become multi planetary – the funding.

TRAPPIST-1d For an Earth-like albedo of 0.3, the planet’s equilibrium temperature is around 258 K (−15 °C; 5 °F), very similar to Earth’s at 255 K (−18 °C; −1 °F).[6]
Doug Vakoch sends music to Luyten b (more commonly known as GJ 273b) is a confirmed exoplanet, likely rocky, orbiting within the habitable zone of the nearby red dwarf Luyten’s Star.
? at best: nobody is living there – at worst they interpret “Justin Biber” and “Shakira” songs as a threat – and launch a preventive strike with their singularity nuke against us (basically installing a black hole near our planet – destroying the whole solar system).
(this is a bit funny… but it is actually one REAL REASON GIVEN why US-military needs faster, better, more nukes with super secure launch codes like 00000000) that could kill all life on earth, before anyone reaches any exoplanets or even Mars ?)
Luyten b is a Super-Earth of around 3 times the mass of Earth and receives only 6% more starlight than Earth, making it one of the best candidates for habitability.[1] In October 2017 and 2018, the nonprofit organization METI (Messaging Extraterrestrial Intelligence) sent a message containing dozens of short musical compositions and a scientific “tutorial” towards the planet in hopes of contacting any potential extraterrestrial civilizations.[3]

According to this NASA 3D simulation (it is 12 light years away (very far) says wiki) and not exactly in the habitable zone.
“Transmission 2, will be sent out on 14th, 15th and 16th of May sending signals from artist such as: Alva Noto,
Daito Manabe… techno and electrodes in your face? seriously? X-D
Kate Tempest, Darko Keteleš, Juana Molina, Pavel Apisov, Yuzo Koshiro, Zora Jones and others.” (src)
