Funding development

Realistically how much runway is left for development, and can this continue to be supported via donation or via extending the Beam treasury block allocation (w/o increasing max supply of course). I know it was discussed how much Beam was left and then maybe some other funds to support hosting and such, and some ideas were proposed to apply for grants, and other partnerships or VC funding would be great, but even just a simple Beam block allocation continuation if nothing else is possible?
